🌳🐐 Think twice before planting mahogany!
It may be good for timber, but mahogany harms our forests and poses risks to native wildlife and livestock like goats. Its leaves contain toxins that can cause digestive issues—and it pushes out native trees that support biodiversity.
🌱 Choose native, beneficial trees that feed both your land and your animals.
📌 Save and share to spread awareness!
🌳 Impact of Mahogany in the Philippine Forest
❌ 1. Disrupts Native Biodiversity
Low leaf litter diversity: Mahogany produces allelochemicals (natural herbicides) that inhibit the growth of native plants under and around it.
Monoculture effect: Mahogany plantations often outcompete native tree species like narra, molave, and balete.
Reduces forest food sources for native insects, birds, and mammals.
❌ 2. Poor Soil Health
Leaf litter is slow to decompose, offering little organic matter and nutrients for forest floor organisms.
Allelopathic chemicals in the leaves and bark inhibit natural soil regeneration and undergrowth.

🐾 Effects on Native Animals
⚠️ 1. Loss of Habitat
Birds, pollinators, and mammals that depend on native trees avoid mahogany stands because the tree doesn't support diverse wildlife (few flowers, fruits, or shelter).
It reduces populations of native insects, which are critical food sources.
⚠️ 2. Toxicity Risk
The seeds, leaves, and bark contain bitter alkaloids and limonoids that are toxic to many herbivores and insects.

🐐 Effects on Domestic Animals (e.g., Goats)
❗Not Safe for Feeding
Mahogany leaves are toxic to goats and other livestock.
Contain limonoids and alkaloids that may cause:
🧪 Diarrhea
🤢 Appetite loss
☠️ In severe cases, poisoning
Bitter and unpalatable—goats may avoid eating them unless desperate.

✅ What You Can Do Instead
Prefer planting native and multi-purpose trees like:
Narra, Molave, Balete, Bignay, Duhat, Banaba
