Newsletter: Bird poop to the rescue: Using bird perches for forest regeneration

[THIS IS A PRESS RELEASE]

By: Dr. Jelaine L. Gan

Reforestation activities typically involve planting trees in degraded areas. However, tree planting is resource-intensive, requiring labor for the planting and more importantly nurturing of the seedlings, and may be expensive and limited by seedling supply. Moreover, there is always a question of whether the right plant species (i.e., native rather than non-native economically important species) are being planted to benefit biodiversity. 

Newsletter: Investigating the role of bird perches in reforestation

[THIS IS A PRESS RELEASE]

Reforesting damaged forests is crucial for fighting climate change and protecting wildlife. One common way to do this is by planting trees, but this can be expensive and labor-intensive. A cheaper and more effective approach is Assisted Natural Regeneration (ANR), which can involve the use of bird perches to attract fruit-eating birds that can help spread tree seeds and speed up the natural regeneration of the forest.

Researchers from the University of the Philippines - Diliman College of Science Institute of Biology (UPD-CS IB), the Norwegian Institute for Nature Research, and the UK’s Newcastle University aim to embark on a systematic review and meta analysis of previous studies and observations to figure out how well artificial and natural perches work in increasing seed dispersal and seedling growth on degraded areas.
