Why Do Rainforests Matter? | BCCP

Written by Dr. Matt McLennan | July 14, 2026

Rainforests are often discussed in terms of climate — carbon storage, oxygen production, rainfall patterns — and all of that is genuinely important. But rainforests also matter for a more immediate reason: they are the only home an enormous share of the planet's biodiversity has, including species, like wild chimpanzees, that cannot survive anywhere else.

Rainforests as carbon stores

Tropical forests hold vast amounts of carbon in their trees, soil, and vegetation, and clearing them releases that carbon into the atmosphere while simultaneously removing the forest's ongoing capacity to absorb more. This dual effect — releasing stored carbon and losing future absorption capacity — is one reason deforestation is such a significant driver of climate change globally.

Rainforests and local rainfall patterns

Forests play a direct role in regional water cycles, releasing moisture that contributes to rainfall patterns well beyond the forest's own boundaries. Large-scale forest loss has been linked to reduced and less predictable rainfall in surrounding agricultural areas — meaning deforestation can directly undermine the same farming communities that often drive it in the first place, a genuinely difficult feedback loop.

Rainforests as biodiversity reservoirs

Tropical rainforests host a disproportionate share of the world's species relative to their land area, many of which are highly specialised to that specific forest habitat and cannot survive elsewhere. Wild chimpanzees are a clear example — an entire species, alongside countless other plants and animals, dependent on forest habitat that, once cleared, doesn't simply grow back to its original state within any human-relevant timeframe.

Forest fragments matter too

Conservation attention often focuses on large, intact rainforest blocks, but smaller forest fragments — like those scattered across farmland in Western Uganda — still matter enormously, particularly for species capable of surviving in fragmented habitat if the remaining patches are managed and reconnected well. This is exactly the landscape the Bulindi Chimpanzee & Community Project works in: not a single vast protected reserve, but a patchwork of forest fragments that still supports a genuine wild chimpanzee population.

Local, human benefits of forest

Beyond global climate and biodiversity value, forest provides direct, tangible benefits to nearby communities — firewood, building materials, and in some cases food and medicine — meaning forest loss doesn't just affect distant climate statistics, it directly affects the livelihoods of the people living closest to it, often the very communities driving small-scale clearing out of genuine economic need.

Why restoring forest fragments is a real, achievable strategy

Because forest fragments can still support meaningful wildlife populations if properly managed, targeted efforts like forest enrichment planting and corridor replanting between fragments offer a genuinely achievable conservation strategy, even in a landscape where a return to unbroken, pristine forest simply isn't realistic anymore.

The Western Uganda picture

The Bulindi Chimpanzee & Community Project's work reflects exactly this pragmatic approach — restoring and reconnecting the forest that remains, rather than treating fragmentation as an unsolvable problem. It's slower and less dramatic than protecting a single vast wilderness, but it's a strategy suited to the landscape as it actually exists today.

Quick FAQ

Do all rainforests provide the same climate benefits? Broadly similar in function, though scale matters — a small forest fragment provides real but proportionally smaller carbon storage and rainfall benefits than a vast, continuous rainforest block.

Can a cleared rainforest area ever fully recover? Partial recovery through replanting and natural regeneration is possible over years to decades, but recreating the full original species complexity typically takes far longer than any human-relevant restoration timeline.

Why do rainforests hold so much more biodiversity than other habitats? Stable, warm, wet conditions over long evolutionary timescales have allowed rainforests to support and sustain an unusually high number of specialised, often highly localised species.

Local action, global relevance

Restoring even a modest forest fragment contributes real, measurable value — carbon storage, rainfall stability, and habitat for species like wild chimpanzees — regardless of its size relative to global rainforest totals. Meaningful conservation doesn't require saving an entire biome at once; it can start with one specific, well-managed landscape. Reforestation projects also frequently deliver secondary benefits beyond their primary conservation goal, including improved local water quality and reduced soil erosion, making forest restoration a genuinely multi-purpose investment rather than a narrowly single-issue environmental intervention. Community-led reforestation efforts in particular have shown encouraging results across several African landscapes, demonstrating that local communities, given the right support and incentives, can be effective long-term stewards of restored forest rather than requiring purely external management indefinitely.

Ultimately, understanding rainforests as both a global climate asset and a specific, local lifeline for species like wild chimpanzees makes the case for their protection considerably harder to dismiss as someone else's problem.

These community-led models are increasingly viewed as a template worth replicating elsewhere, offering a genuinely scalable approach to forest restoration that doesn't depend entirely on external funding and management indefinitely.
