About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more...

A six-year-old project to return giant tortoises to the wild in Madagascar could result in thousands of the 350kg megaherbivores re-populating the island for the first time in 600 years.

The first group of Aldabra giant tortoises (Aldabrachelys gigantea) were brought in from the Seychelles in 2018, and have been reproducing on their own since. A group of ecologists explain how reintroducing this tortoise to areas degraded by cattle grazing will help restore the island’s forests, grassy woodlands and shrublands of the past. It could also help prevent devastating forest fires in future.

Animals like this where lots of babies never made it to adulthood naturally are really easy to reintroduce.

They're just sheltering the young till they're big/strong enough that smaller predators cant fuck with them. Then releasing them into the wild.
