It is considered to be a mega – diversity country because of the exceptional diversity in ecosystems, species and genetic resources found within its 7,100 island territory. … The overexploitation of natural resources, reduced the forests to an alarming 24% from its original cover.
Why is the Philippines considered to be a biodiverse country?
The Philippines is one of the 17 mega biodiverse countries, containing two-thirds of the Earth’s biodiversity and 70 percent of world’s plants and animal species due to its geographical isolation, diverse habitats and high rates of endemism. The Philippines’ biodiversity provides several ecosystem services.
What is biological hotspot and why Philippines is considered to be part of it?
It is generally accepted that the Philippines terrestrial and marine habitats contain some of the richest biodiversities of flora and fauna, and its waters are considered a part of the biodiverse Coral Triangle. Further, many of these organisms are endemic to the Philippines.
What is considered biodiversity hotspot?
To qualify as a biodiversity hotspot, a region must meet two strict criteria: It must have at least 1,500 vascular plants as endemics — which is to say, it must have a high percentage of plant life found nowhere else on the planet. A hotspot, in other words, is irreplaceable. … In other words, it must be threatened.
Why Philippines is one of the hottest hotspots in the world?
The mountainous areas on the island of Luzon are rich in plants and animals and have a relatively high forest cover compared to the lowlands (Heaney 2001;Posa et al. 2008). … … The Philippines are classified as a global biodiversity hotspot with high endemism and value for conservation (Myers et al.

The importance of Biodiversity hotspots is: 1. Preservation: They provide an ecoregion for the preservation and conservation of many endemic species. 2. Development: They help in developing a healthy ecosystem.
Why is it important to identify biodiversity hotspots quizlet?
Biodiversity hotspots are important because it is within these unique ecosystems that many rare and endangered species exist. Therefore, it is important to study and protect these areas.
What is the primary reason for targeting biodiversity hotspots for conservation?
What is the primary reason for targeting “biodiversity hotspots” for conservation? The number of species threatened far exceeds our capacity to protect them and we should therefore concentrate on areas of highest species diversity. You just studied 20 terms!
What is diversity and biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
