Komodo National Park is celebrated for its reptiles, but the landscape those reptiles inhabit is shaped, above all, by plants. A fire-maintained mosaic of open savanna, dry monsoon forest, and patches of denser woodland covers the park's islands, all adapted to one of the most seasonal climates in Indonesia. The flora here is not a lush tropical rainforest — it is a tough, drought-hardened, fire-tolerant assemblage characteristic of the dry Lesser Sunda Islands and the broader Wallacea biogeographic zone, with the iconic lontar palm standing as its most visible symbol.

A Fire-Shaped, Drought-Hardened Landscape
The park's islands — Komodo, Rinca, Padar, Gili Motang, and surrounding islets — lie in the Sape Strait between Sumbawa and Flores at roughly 8–9°S latitude. Despite this tropical position, the region sits in the rain shadow of Australia's seasonal dry air masses, producing a climate more akin to semi-arid East Africa than to the wet rainforests of Borneo or Sumatra. Annual rainfall is typically below 1,000 mm and falls almost entirely between December and March, leaving the landscape parched for eight months of the year.
That aridity, combined with centuries of seasonal burning by local communities, has produced a vegetation mosaic dominated by open grassland and deciduous woodland. Fire is not simply a disturbance here — it is a structuring force that continuously pushes back woody vegetation, recycles nutrients into the thin soils, and maintains the open sight-lines that grazing mammals and hunting Komodo dragons both depend on. Understanding the park's flora requires understanding fire as its primary ecological engineer.
Wallacea and the Lesser Sunda Floristic Character
Komodo National Park falls within Wallacea — the biogeographic transition zone between Asia and Australia. Its flora reflects this position: predominantly of Asian (Malesian) affinity, but increasingly influenced by dry Australian and Indo-Pacific elements moving eastward. Monk, de Fretes & Reksodiharjo-Lilley (1997) note that the dry forests of Nusa Tenggara share floristic elements with seasonal forests in Java, Sulawesi, and the Lesser Sundas rather than constituting a unique endemic flora. True single-island endemics are rare; the park's botanical value lies in its well-preserved examples of a threatened dry-forest ecosystem type.
Savanna Grasslands: The Dominant Vegetation
Open tropical savanna covers the majority of lower-elevation terrain on all the major islands. From the air or from a hilltop, the gold-and-amber hillsides interrupted by solitary palms are the park's most iconic visual — an image closer to East African grassland than any Asian stereotype of tropical forest.
Dominant Grasses
Two grasses overwhelmingly define the savanna matrix. Themeda triandra (kangaroo grass) is a tall, tufted perennial that turns bronze-gold in the dry season and is well adapted to fire — its growing points sit close to the ground, protected by the soil, and it resprouts vigorously after burning. Heteropogon contortus (black speargrass) is a companion species of similar habit, recognisable by its twisted, black-tipped seeds that drill into soil and fur alike. Both species are characteristic of fire-maintained tropical grasslands across Southeast Asia, Australia, and Africa — they are not endemic to Komodo but are precisely the species one would expect in this dry, fire-prone climate.
Other grasses recorded in the savanna include species of Eulalia, Chrysopogon, and Aristida, forming a species-poor but structurally important ground layer. This low diversity is typical of fire-climax grassland worldwide.
Forbs, Shrubs, and Scattered Trees
The grass matrix is punctuated by drought-deciduous shrubs and small trees, notably Ziziphus spp. (jujube relatives with tough, spiny branches), scattered individuals of Cassia and Acacia, and various forbs that exploit the brief wet season before dying back. The lontar palm, described in detail below, rises above the grassland as its most dramatic woody element.
The Lontar Palm: Icon of the Dry Islands
No plant is more deeply associated with Komodo and the wider dry Lesser Sundas than the lontar palm, Borassus flabellifer (family Arecaceae). Tall, solitary, and fan-leaved, the lontar is the biological and cultural anchor of the park's savanna landscape.
Ecology
Borassus flabellifer is a large fan-palm reaching 20–30 m, with a stout grey trunk and a crown of stiff, pleated leaves up to 1.5 m across. It is dioecious — male and female flowers occur on separate individuals — and produces large, dark brown fruits containing three seeds embedded in fibrous flesh. The palm tolerates extreme seasonal drought through a deep, extensive root system that accesses groundwater unavailable to most other plants; it can persist through the entire dry season without visible stress while surrounding grasses turn brown and die back.
Ecologically, standing lontar palms provide critical services in the savanna. Their crowns are the primary nesting and roosting sites for large birds, including orange-footed scrubfowl (Megapodius reinwardt) and yellow-crested cockatoos (Cacatua sulphurea). The fruits, when they fall and split, are consumed by Timor deer, wild boar, and water buffalo — an indirect but real contribution to the prey base of the Komodo dragon. The palm is also largely fire-resistant: its thick trunk and elevated crown survive the low-intensity surface fires that sweep through the grass annually.
Cultural and Economic Importance
Outside the park, lontar is one of the most useful trees in eastern Indonesia. The inflorescences, when tapped before opening, yield a sweet sap that can be drunk fresh as a health tonic, fermented into a mildly alcoholic drink (tuak or sopi), or boiled down to produce palm sugar (gula lontar). Leaves are woven into baskets, mats, fans, and the traditional lontar manuscripts (the name "lontar" itself comes from the Javanese for the palm-leaf manuscripts written on dried fronds). Fruits are eaten both ripe and unripe, and the timber, while difficult to work, is used for construction in some communities. The park protects areas of natural lontar woodland, but the tree has been cultivated and semi-cultivated throughout the region for millennia, so it is difficult to draw a sharp line between natural groves and those with human encouragement.
Tropical Deciduous (Monsoon) Forest
In moister microsites — shaded valleys, north-facing slopes, and terrain where soils are somewhat deeper — the savanna gives way to tropical deciduous forest, also called monsoon forest or dry forest. This vegetation type is richer in species than the grassland but still strikingly seasonal: the canopy sheds most of its leaves in the long dry season, reducing water loss and turning the forest a dull grey-brown before the rains bring a flush of new growth.
Canopy and Sub-canopy Species
The dominant canopy trees are drawn from a suite of drought-adapted species characteristic of dry forests across Nusa Tenggara and Sulawesi:
- Tamarindus indica (tamarind) — one of the most conspicuous trees in the park, with distinctive pinnate leaves and rough, dark bark. It is drought-deciduous but often holds leaves longer than neighbours. Its sour pods are consumed by deer and birds and have been used by local communities for food and medicine for centuries. Tamarind is of probable African origin but has been naturalised across tropical Asia for so long that it functions as a native component of the dry forest here.
- Sterculia foetida (wild almond or fetid sterculia) — a tall tree with a distinctive spreading crown and large, lobed leaves; the name refers to the unpleasant smell of its flowers. Its large woody follicles contain edible seeds roasted by local communities, though the unripe fruit is mildly toxic.
- Schleichera oleosa (lac tree or Ceylon oak) — a semi-evergreen tree with compound leaves and smooth, flaking grey bark. It produces an oil-rich seed used in cooking and cosmetics across South Asia and is sometimes host to lac insects. It is a characteristic element of dry seasonal forests in the Lesser Sundas.
- Ziziphus spp. — spiny, small-leaved trees and large shrubs common at forest margins and in disturbed areas; their small fruits are consumed by birds and mammals.
- Cassia spp. (now partly reclassified under Senna) — leguminous trees and shrubs with yellow flowers, widespread in open and disturbed forest edges throughout the tropics.
Other recorded elements of the monsoon forest include Pleiogynium timoriense (Burdekin plum), species of Ficus (figs, which are important fruit sources for many animals), Albizia, Pterocarpus, and various understorey shrubs and climbers. Bamboo (Dendrocalamus or Bambusa spp.) occurs locally in moister gullies, providing dense cover used by young Komodo dragons and other small animals.
Ecological Role in the Dragon's Life Cycle
Monsoon forest patches are disproportionately important to the Komodo dragon despite covering a smaller area than savanna. Hatchling and juvenile dragons spend their first two to three years almost entirely in trees, sheltering from cannibalism by adults; the dense, layered structure of monsoon forest — with its fig-laden branches and tangled understorey — provides the refuge that open grassland cannot. As documented by Auffenberg (1981), the transition from arboreal juvenile to terrestrial adult is facilitated by the heterogeneous habitat mosaic the park preserves.
Quasi-Montane Forest on High Peaks
Quasi-montane forest on Komodo and Rinca islands occupies the highest elevations — around 735 m on Mount Satalibo (Komodo) — where orographic rainfall and cloud interception create marginally more humid conditions than the surrounding lowlands. This forest type supports a higher proportion of evergreen species and a richer epiphyte flora, including mosses, ferns, and orchids, than the deciduous monsoon forest that covers the majority of both islands.
The highest elevations of Komodo Island (Mount Satalibo, ~735 m) and Rinca Island receive marginally more orographic rainfall and experience cooler, cloud-intercepting conditions for part of the year. Here, the deciduous forest gives way to a denser, more humid woodland with a higher proportion of evergreen species and a richer epiphyte flora — mosses, ferns, and occasional orchids appear on trunks and larger branches where they would be absent on drier lower slopes.
This "quasi-cloud forest" or upper montane element is localised, covering only a small fraction of the park's land area. It has not been as thoroughly surveyed as the more accessible lowland vegetation, and it likely harbours a higher density of more range-restricted plant species than the better-known savanna and dry forest below. It remains an understudied component of the park's flora.
Mangroves and Coastal Vegetation
Mangrove forests fringe the sheltered bays and estuaries of Komodo and Rinca islands, forming a structurally distinct coastal habitat dominated by Rhizophora species on the seaward margins and Avicennia species in more brackish inner zones. These forests serve as nursery habitat for reef fish, foraging grounds for Komodo dragons and water monitors, and coastal stabilisation structures that reduce erosion in the high-energy tidal environment.
Fringing mangrove forests line sheltered bays and estuaries on the northern and eastern coasts of the major islands, particularly around Loh Liang on Komodo and Loh Buaya on Rinca. The mangrove flora is typical of Indo-Pacific systems: Rhizophora spp. dominate the seaward fringe with their distinctive arching prop roots; Avicennia spp. occupy more brackish inner zones; Bruguiera and Sonneratia occur where conditions allow. These forests are modest in extent but ecologically crucial — they serve as fish nurseries, shorebird feeding grounds, and natural buffers against coastal erosion, a role that grows more significant as sea-level rise accelerates.
Beach and strand vegetation occupies sandy and rocky shores above the high-tide line. Characteristic species include Ipomoea pes-caprae (beach morning glory), Scaevola taccada (beach naupaka), Casuarina equisetifolia (she-oak) on some beaches, and scattered coastal scrub. These are widespread Indo-Pacific strand species, not park endemics, but they stabilise shorelines and provide nesting habitat for sea turtles.
Drought and Fire Adaptations
The flora of Komodo National Park has been shaped by two overwhelming selective forces: an eight-month dry season and recurrent fire. The adaptations that result are visible throughout the landscape.
Drought Adaptations
- Deciduousness: the majority of woody plants drop their leaves at the onset of the dry season, drastically reducing transpiration. In the most extreme cases, trees stand leafless for five to six months, surviving on stored carbohydrates.
- Deep root systems: trees such as tamarind and lontar palm develop extensive lateral and tap roots that reach well below the dry surface soil to access residual soil moisture or shallow groundwater.
- Reduced leaf area and thick cuticles: many shrubs and pioneer species have small, tough, waxy leaves that minimise water loss when the plant cannot shed them entirely.
- Geophytes and annual herbs: the understorey includes a small flora of geophytic plants (bulbs, corms, tubers) and annual herbs that complete their life cycle rapidly during the wet season and persist through the dry period as dormant underground organs.
Fire Adaptations
- Protected meristems: grasses such as Themeda triandra and Heteropogon contortus keep their growing points at or below ground level, allowing rapid resprouting after surface fire burns off the above-ground biomass.
- Thick bark: savanna trees including tamarind and lontar palm have thick, insulating bark that shields the cambium from the heat of fast-moving grass fires.
- Post-fire flushing: many deciduous trees flush new leaves within days to weeks of fire, exploiting the ash-fertilised soil before competing vegetation recovers.
- Serotiny and heat-triggered germination: some pioneer shrubs and trees have seeds that germinate most effectively after heat treatment, exploiting the open, ash-covered ground that fire creates.
Fire Ecology: How Savanna Is Maintained
The open savanna that dominates the park's lowlands is not a stable climax vegetation — it is a fire-maintained grassland. Without regular burning, the grasses would accumulate a dense thatch that itself becomes highly flammable; simultaneously, woody species would progressively encroach and, over decades, transition the landscape toward closed woodland or forest. Fire periodically resets this succession, killing or top-killing woody seedlings and saplings before they can establish a canopy.
Dry-season fires have been set by local communities for centuries, primarily to improve grazing for deer and cattle and to facilitate hunting. These anthropogenic fires have, paradoxically, maintained the very habitat that the Komodo dragon depends on: open savanna with high deer density provides the foraging conditions that sustain the park's large lizard population. The relationship between fire, grass, herbivore, and predator is therefore an ancient, human-mediated ecological loop.
Park management faces a genuine challenge here. Total fire suppression would likely lead to forest encroachment and a reduction in prime dragon habitat; uncontrolled late-dry-season fires can be severe enough to kill mature trees and damage monsoon forest patches. Balai TN Komodo (the park authority) has worked toward a managed fire regime that retains early-dry-season burning as a landscape tool while protecting forest patches and sensitive habitats from high-intensity late-season fires.
Fire and the Komodo Dragon: An Indirect Dependence
The Komodo dragon does not interact with fire directly, but its ecology is fire-dependent at one remove. Open savanna maintained by burning supports dense populations of Timor deer (Rusa timorensis), the dragon's primary prey. Were fire suppressed and the savanna converted to closed woodland, deer densities would fall, reducing the prey base and ultimately the carrying capacity for dragons. In this sense, fire — mediated through vegetation — is as fundamental to the dragon's survival as the dragon's own adaptations.
Notable and Useful Species
Several plant species in Komodo National Park merit particular mention for their ecological or cultural significance. Bamboo stands in moist gullies provide structural refuge for juvenile Komodo dragons and small vertebrates. The lontar palm (Borassus flabellifer) — characteristic of the open savanna — provides food and materials for local communities. The introduced Lantana camara has become an invasive problem, spreading through disturbed areas and outcompeting native ground flora.
Beyond the dominant species described above, several plants merit particular mention for their ecological or cultural significance within the park.
Bamboo
Stands of bamboo — likely Dendrocalamus spp. or related genera — occur in moist gullies and valley floors. Bamboo groves are structurally complex micro-habitats used as refugia by juvenile Komodo dragons and various small mammals and birds. Local communities traditionally use bamboo culms for construction, containers, and musical instruments.
Wild Fig (Ficus spp.)
Several species of fig occur in the monsoon forest and at forest margins. Figs are keystone food resources — their asynchronous fruiting means that at least one species is in fruit at almost any time of year, providing food for fruit bats, birds, macaques, and lizards when other resources are scarce. The fig–fig wasp mutualism (each fig species has a specialised pollinating wasp) makes fig trees among the most ecologically complex organisms in the ecosystem.
Tamarind (Tamarindus indica)
Already noted as a canopy dominant, tamarind deserves additional mention for its cultural role. The sour pulp of the ripe pod is used in local cooking throughout eastern Indonesia as a souring agent in fish dishes and sauces. The bark has traditional medicinal applications, and the hard, dense wood is valued for tools and construction where it can be sustainably harvested outside park boundaries.
Beach Morning Glory (Ipomoea pes-caprae)
This creeping vine colonises sand beaches across the entire Indo-Pacific region and is one of the most visible plants on the park's sandy shores. Its deep root system stabilises dune faces, and its large pink-purple flowers are visible year-round. It is of no special conservation concern but illustrates the park's connection to a wider Indo-Pacific coastal flora.
The Question of True Endemism
The word "endemic" is frequently applied loosely to Komodo's plants, and some clarification is essential. A strictly endemic species is one whose entire natural global range is confined to a specific area — in the most restricted sense, to a single island or the park itself. By this definition, the flora of Komodo National Park has very few, if any, confirmed strict endemics.
Most of the park's characteristic plants — Borassus flabellifer, Themeda triandra, Tamarindus indica, Sterculia foetida, Schleichera oleosa — are widespread across tropical Asia, the Indo-Pacific, or the entire Old World tropics. Even species with a more restricted distribution in Nusa Tenggara are typically shared across several of the Lesser Sunda Islands or the wider Wallacean region, rather than being unique to Komodo.
As Monk, de Fretes & Reksodiharjo-Lilley (1997) document, the Lesser Sundas as a whole have lower plant endemism than the "core" Wallacean islands of Sulawesi and Maluku, in part because the seasonally dry Lesser Sunda chain is younger geologically and has been more susceptible to long-distance dispersal events. The park's botanical value therefore lies not in a high count of strict endemics but in the quality and intactness of a vegetation type — dry tropical savanna and monsoon forest — that has been severely degraded across most of its range in Indonesia by agriculture, overgrazing, and fire regime change.
That said, the higher-elevation forest patches on Komodo and Rinca have not been thoroughly surveyed by modern botanical methods, and it is possible that restricted-range species await formal description. Caution and further research, rather than inflated claims, are the appropriate responses to current uncertainty.
Threats and Conservation
The flora of Komodo National Park faces several interacting threats, the most immediate being alteration of the fire regime. If burning becomes more frequent, more extensive, or shifts later into the dry season when fires burn hotter, monsoon forest patches and their biodiversity will contract further into refugia on rocky slopes. Introduced invasive plants, particularly Lantana camara, and goat grazing around settlements compound vegetation change.
The park's flora faces several interacting threats, some of long standing and some emerging.
Fire Regime Change
The greatest near-term risk to forest patches is alteration of the fire regime. If burning becomes more frequent, more extensive, or shifts to later in the dry season (when fires burn hotter and kill larger trees), monsoon forest patches and the biodiversity they contain could be progressively reduced. Climate change is expected to extend and intensify dry seasons across the region, increasing fire risk.
Invasive Species
Several introduced plant species have established in disturbed areas within and around the park. Invasive grasses, in particular, can alter fire regimes by providing a continuous, highly flammable fuel bed that carries fire into previously fire-resistant forest margins. Control of invasive plants in a large, remote park with limited resources is a persistent challenge for Balai TN Komodo.
Overgrazing by Introduced Herbivores
Water buffalo (Bubalus bubalis), introduced by past human settlement, are present at considerable densities on some islands. Heavy grazing suppresses grass regeneration, compacts soils, and can retard woody regrowth after fire, altering vegetation structure in ways that may disadvantage native species over generalist, disturbance-tolerant ones.
Climate Change
UNESCO and the IUCN have flagged climate change as a long-term existential threat to the park, primarily through sea-level rise threatening coastal and mangrove habitats and through shifts in rainfall seasonality. A longer, more intense dry season would favour the already-dominant fire-adapted grasses at the expense of monsoon forest, potentially simplifying the vegetation mosaic and reducing habitat diversity.
Conservation Response
The park's designation as a UNESCO World Heritage Site (1991) and a strict national park affords strong legal protection against clearance and conversion. Balai TN Komodo has developed management plans that address fire control, invasive species monitoring, and community liaison. The relative inaccessibility of the park's interior has also, in practice, limited the degree of botanical disturbance compared to other Indonesian protected areas of similar size.
Myths vs Facts
| Myth | Fact |
|---|---|
| Komodo National Park is covered in tropical rainforest. | No. The dominant vegetation is open tropical savanna grassland and dry deciduous (monsoon) forest. Annual rainfall is often below 1,000 mm — far too low for rainforest. The landscape is closer to semi-arid East Africa than to Borneo. |
| Nothing grows in the dry season — the islands are barren. | The savanna grasses die back and the forest trees drop their leaves, but the landscape is far from bare. Lontar palms, tamarinds, and other deep-rooted species remain green. Root systems, dormant bulbs, and grass crowns persist underground, ready to flush with the rains. |
| The park has many plant species found nowhere else on Earth. | Strict single-island endemics are rare to absent. Most species are widespread Wallacean or Lesser Sunda taxa. The park's value is the quality and intactness of a threatened dry-forest ecosystem, not a high count of unique species. |
| The lontar palm was planted by people throughout the park. | Lontar is native to this dry zone and self-propagates naturally. Human communities have encouraged it and used it for millennia, but it is not an introduced species — it belongs ecologically to the dry Lesser Sunda landscape. |
| Fires in the park are entirely destructive and should be prevented. | Low-intensity early dry-season fires are a natural and human-maintained ecological process that keeps the savanna open and supports high prey densities for Komodo dragons. Complete fire suppression would likely alter the habitat negatively. Managed fire, not fire exclusion, is the conservation goal. |
| Tamarind trees in the park are the same as the cultivated variety grown for food. | Tamarindus indica is the same species, but the park's trees are wild or semi-wild individuals. The species is of likely African origin but has been naturalised across tropical Asia for so long that it functions ecologically as an integrated component of the monsoon forest. |
Practical Takeaways
- The savanna is the park's signature vegetation — the golden grassland dotted with lontar palms that makes aerial and hillside views so distinctive. It is maintained by fire, not just climate.
- Visit after the first rains (December–January) to see the most dramatic vegetation transformation — the same hillsides that were amber-brown in October flush bright green within days of the first significant rainfall.
- Look up in the monsoon forest — figs, wild tamarind, and Sterculia form a canopy that shelters juvenile Komodo dragons in their first years; the forest patches are as important to the park's ecology as the open savanna.
- Do not remove or damage plants — all vegetation within the park is protected under national park regulations. Collecting plant material, including seeds, pods, and leaves, requires a scientific permit.
- Appreciate what "endemic" really means — the park's flora is not remarkable for strict single-island endemics, but it preserves one of the best-remaining examples of dry Wallacean savanna and monsoon forest in Indonesia. That is its genuine botanical distinction.
- Bamboo groves and fig trees deserve attention — these structural keystones are easy to overlook but are among the most ecologically important plants in the park for wildlife.
Frequently Asked Questions
How many plant species grow in Komodo National Park?
Estimates vary by survey and methodology. Figures of approximately 250–300 vascular plant species are commonly cited for the park's terrestrial flora, but a comprehensive, modern botanical inventory does not appear to exist in the published literature. Monk, de Fretes & Reksodiharjo-Lilley (1997) provide the most thorough regional context; park-level totals should be treated as approximate.
Are there any plants found only in Komodo National Park?
Strict single-island or single-park endemics have not been definitively confirmed in the published scientific literature for Komodo's flora. The park's characteristic species are generally shared with other dry Lesser Sunda and Wallacean habitats. The higher-elevation forest patches remain incompletely surveyed, and restricted-range species may yet be described — but claims of high endemism should be treated sceptically until supported by peer-reviewed botanical work.
Why does the park look so dry and brown for most of the year?
The park experiences one of the driest climates in Indonesia, with a pronounced eight-month dry season (approximately April–November) during which rainfall is negligible. Deciduous trees shed their leaves to reduce water loss, grasses die back to their fire- and drought-resistant crowns, and the landscape takes on its characteristic golden-brown appearance. This is normal and healthy, not a sign of ecological degradation.
Is the lontar palm native to the park, or was it introduced?
Borassus flabellifer is native to the dry Lesser Sunda region and is a natural component of the dry-forest and savanna flora. Human communities have used and encouraged it for millennia, which may have influenced its local distribution, but it is not an introduced species in the sense of being foreign to the region's flora.
What role does fire play in maintaining the park's vegetation?
Fire is the dominant ecological process shaping the savanna. Seasonal burning — historically set by local communities and now managed by the park authority — kills woody seedlings before they can convert grassland to forest, recycles nutrients, and maintains the open habitat that supports high densities of Timor deer, which in turn sustain the Komodo dragon population. A managed fire regime is therefore an active conservation tool, not simply a threat to be suppressed.
Can I see flowering plants on a typical park visit?
Yes, though the timing matters. The peak of flowering activity follows the onset of the wet season (December–January), when deciduous trees flush new leaves and flowers simultaneously. The dry season (April–November) offers fewer flowers in the forest interior, but savanna forbs, coastal vegetation, and some drought-adapted shrubs flower throughout the year.
Are any park plants used medicinally or by local communities?
Yes. Tamarind (Tamarindus indica) is used as a souring agent in cooking and has traditional medicinal applications across eastern Indonesia. Lontar palm (Borassus flabellifer) is tapped for sap to make palm sugar and alcoholic beverages, and its leaves are woven into mats and containers. Schleichera oleosa seeds yield a cooking and cosmetic oil. Within the park boundaries, collection is prohibited without permits; these uses are documented in surrounding communities.
How is the park's flora threatened by climate change?
Climate projections for the region suggest longer and more intense dry seasons, increased fire frequency and severity, and sea-level rise affecting coastal and mangrove habitats. These changes would likely favour fire-adapted grasses at the expense of monsoon forest, reduce the diversity of the vegetation mosaic, and erode mangrove buffers along the coast. UNESCO has flagged climate change as a long-term threat to the park's Outstanding Universal Value.
