In order for a plant to be considered carnivorous, it must 1) attract prey, 2) capture prey, and 3) digest the prey. Many plants are able to do the first two criteria, but few actually do all three. Some fall into a gray area and are considered quasi or semi carnivorous.
The Mid-Atlantic Carnivorous Plant Society is a group of carnivorous plant enthusiasts from Pennsylvania, Maryland, Delaware, New Jersey, and the surrounding area. They hold four meetings throughout the year, go on trips, and exchange cultivation advice.
Worldwide, there is an ever increasing danger of the reduction and loss of Carnivorous Plants. Most of these threats are from human encroachment upon the habitats of Carnivorous Plants, which are often slow-growing plants.
