Gymnadenia conopsea
There are 627 flora species identified by Serra and Carvalho(1989) as under pressure and considered endangered, which included two medicinal plants: tutsan ("Hypericum androsaemum") and sundew ("Drosera rotundifolia"). Based on the protection list of botanical species, and UICN categories: 18 are considered in risk of extinction, 17 are vulnerable and one is rare. They also identified two species as extinct within the park boundaries: a geranium ("Geranium lanuginosum") and fragrant orchid ("Gymnadenia conopsea"). There are three endemic species. Those factors that have been identified that threaten these habitats include: natural and manmade fires, use of forest for fuel wood and agricultural use of habitats.
