Although the Matang Mangrove Forest Reserve (MMFR) in Malaysia is suggested to be a global reference for sustainable silviculture, the impact of greenwood extraction on local biodiversity and ecological functionality remains under-researched. To fill this gap, a rapid biodiversity assessment was conducted using birds as ecological indicators to investigate the effect of mangrove silvicultural management on avian communities. Changes in the diversity of bird species and dietary guilds in response to forest age and management were assessed using the point-count method with visual and auditory observations. This was done in both "productive" forests, consisting of even-aged Rhizophora plantations producing poles and charcoal, and in "protective" forests where extractive activities are prohibited. Remarkably, all avifaunal functional guilds were present in both young "productive" and "protective" forests, however the "productive" forests supported fewer bird assemblages in terms of species richness and total taxonomic diversity compared to the floristically rich and structurally complex "protective" forests. The bird species' response to silvicultural disturbances also varied, with adverse effects especially occurring in functionally specialized species. Furthermore, back mangroves and transition zones to terrestrial forests were found to support a higher avifaunal diversity, possibly because of the enhanced habitat heterogeneity. Finally, this study highlights the use of bird communities as ecological indicators for assessing the quality of mangrove forests, and emphasises the crucial role of habitat and landscape heterogeneity in supporting diverse avifauna and ecosystem functionality highlighting the need for more research integrating mangroves and adjacent ecosystems.
尽管马来西亚的马唐红树林保护区（MMFR）被认为是可持续造林的全球参考范例，但绿材采伐对当地生物多样性和生态功能的影响仍未得到充分研究。为填补这一空白，我们以鸟类作为生态指标进行了快速生物多样性评估，以调查红树林造林管理对鸟类群落的影响。使用点计数法，通过视觉和听觉观察，评估了鸟类物种和食性类群多样性随森林年龄和管理方式的变化。这项评估在两种森林中进行，一种是“生产性”森林，由生产电线杆和木炭的同龄红树人工林组成；另一种是“保护性”森林，禁止进行采伐活动。值得注意的是，所有鸟类功能类群在年轻的“生产性”森林和“保护性”森林中均有出现，然而，与植物种类丰富、结构复杂的“保护性”森林相比，“生产性”森林在物种丰富度和总分类多样性方面支持的鸟类组合较少。鸟类物种对造林干扰的反应也各不相同，特别是功能特化物种受到了不利影响。此外，发现后红树林和向陆地森林的过渡带支持更高的鸟类多样性，这可能是由于栖息地异质性增强所致。最后，本研究强调了将鸟类群落用作评估红树林质量的生态指标，并强调了栖息地和景观异质性在支持多样鸟类和生态系统功能方面的关键作用，突出了需要开展更多整合红树林和相邻生态系统的研究。
