Across Southeast Asia, durian orchards have become iconic: feeding local economies and satisfying international cravings for the “king of fruits.” But here’s the thing: as demand skyrocketed, farmers shifted from their traditional mixed-crop orchards to massive monoculture plantations. Despite durian being Malaysia’s pride and joy, here begs the question: what happens to the wildlife when you replace diverse orchards with single-crop farms? Without this knowledge, farmers cannot make informed decisions about sustainable practices, therefore, conservation efforts remain disconnected from agricultural realities.
Researcher Nursyamin Hanis Binti Zulkifli from Universiti Putra Malaysia set out to answer a simple but crucial question: do traditional mixed-crop orchards support more birds and frogs than monoculture plantations? The research was carried out in three regions: Balik Pulau (Penang), Batu Kurau (Perak), and Lubuk Batu (Terengganu), the perfect regions that host both traditional mixed-crop orchards and large-scale durian plantations. Instead of relying on casual observations, the team deployed bioacoustic recorders that ran 24/7, capturing wildlife sounds without researchers hanging around to spook the animals. The result? Genuine, uninterrupted data on what birds and frogs were actually doing.
Convincing orchard owners to get on board for this research is not a walk in the park. Due to the site’s issues, some limitations make it tricky to generalise the research conclusion. Nevertheless, the team found that traditional agroforestry practices genuinely support richer biodiversity compared to monoculture plantations. And landscape-level factors—like how close orchards are to natural forests—matter way more than expected.
Recognising the potential of this project’s ecoacoustics methodology, The Habitat Foundation funded the project. The project promised something valuable: solid baseline data on wildlife in traditionally managed orchards, offering farmers and conservationists a roadmap for sustainable durian production.
