Tropical montane cloud forests; Ecological treasure; Land-use intensity

Introduction

Tropical montane cloud forests are characterized by their yearround moisture, resulting from the frequent condensation of clouds. This unique climate fosters exceptional biodiversity, making these forests some of the most species-rich habitats on the planet. Their importance extends beyond their ecological richness, as they also play a crucial role in climate regulation and water supply to downstream communities [1, 2].

Methodology

The threat of land-use intensity

Increasing human population pressures and agricultural expansion have led to land-use changes in montane cloud forests. These changes range from traditional shifting cultivation to more intensive land uses like agriculture and logging. Land-use intensity, defined by the degree of human disturbance, can have significant consequences for forest structure and biodiversity [3-5].

Local effects on aboveground biomass

At the local level, high-intensity land uses, such as agriculture or logging, can lead to reduced aboveground biomass in montane cloud forests. This is often due to tree removal, habitat fragmentation, and alterations in microclimatic conditions. As trees are removed or disturbed, the ability of the forest to sequester carbon and support diverse wildlife declines [6].

Local effects on tree diversity

Local land-use intensity also influences tree diversity. In areas subject to intensive land use, the composition of tree species may shift, favouring species adapted to disturbance or those with economic value. This can result in a loss of native biodiversity and the disruption of ecological processes that depend on diverse tree communities.

Regional effects on connectivity

At the regional scale, the cumulative impacts of land-use intensity can disrupt connectivity between montane cloud forest patches. Isolated forest fragments become more vulnerable to edge effects, invasive species, and reduced gene flow among populations. This fragmentation threatens the long-term survival of many species and undermines the ecological resilience of these ecosystems [7, 8].

Conservation and sustainable land use

Efforts to conserve tropical montane cloud forests must consider the local and regional effects of land-use intensity. Conservation strategies may involve sustainable land-use practices, reforestation, and protected area networks that facilitate wildlife movement. Engaging local communities in conservation efforts is crucial for achieving lasting success.

The need for global action

The preservation of tropical montane cloud forests is not only a local or regional concern but a global imperative. These forests are essential for maintaining biodiversity, regulating climate, and ensuring the provision of clean water to millions of people downstream.International cooperation and concerted efforts are needed to address the complex challenges posed by land-use intensity in these ecologically sensitive regions.

The intricate relationship between land-use intensity, aboveground biomass, and tree diversity in tropical montane cloud forests underscores the urgent need for conservation and sustainable land management practices. Balancing the needs of local communities with the preservation of these critical ecosystems is a complex but essential task. By understanding the local and regional effects of land use, we can work towards securing the future of these remarkable and invaluable habitats for generations to come [9].

Tropical montane cloud forests are often referred to as biodiversity hotspots due to their remarkable species richness and high levels of endemism. These ecosystems are characterized by a unique combination of cool temperatures, persistent cloud cover, and abundant rainfall, creating a haven for countless plant and animal species.

Land-use intensity in TMCFs

As human populations grow and demands for resources increase, TMCFs are increasingly subjected to land-use changes. Land-use intensity in these regions can include activities such as agriculture, logging, infrastructure development, and urban expansion. These activities can have profound effects on the structure and composition of TMCFs [10 ].

Conclusion

One of the critical aspects of TMCF health is aboveground biomass, which refers to the amount of living and dead plant material above the forest floor. Recent research has revealed that higher levels of land-use intensity within TMCFs often result in reduced aboveground biomass. This loss of biomass can lead to decreased carbon storage capacity and affect the overall health of the ecosystem.
