Large herbivores rely heavily on mud wallows not only for cooling but also to deter biting insects and parasites.
Although Ujung Kulon is a humid tropical forest, seasonal dry periods reduce surface water availability in certain areas. Javan rhinos depend on freshwater sources and mud wallows for thermoregulation and skin protection. When rainfall declines, wallows can shrink or disappear, concentrating animals around fewer water points. In a population under 80 individuals, such clustering increases competition and stress. Water scarcity can also alter plant growth patterns, affecting forage quality. Climate variability therefore interacts directly with demographic stability. Unlike wide-ranging species, Javan rhinos cannot migrate to distant watersheds. Seasonal hydrology now influences extinction risk.

From an ecological standpoint, water availability shapes habitat suitability at micro and macro scales. Reduced access to wallows can elevate heat stress and parasite load. Concentration at limited water sources may also increase disease transmission risk. Park managers monitor hydrological patterns to anticipate stress periods. In small populations, even temporary physiological strain can affect reproductive timing. Environmental fluctuation thus carries amplified demographic consequences.
On a broader level, the situation illustrates how climate variability compounds vulnerability in geographically confined species. A drought that might inconvenience a widespread population could destabilize a localized one. The Javan rhino’s future depends partly on rainfall consistency within one peninsula. Survival rests not only on protection from poachers but on seasonal cloud cover. Hydrology has become a conservation variable.
