The Effects of Protected Areas in Nepal as a Barrier Against Plant Invasions Are Associated With Lower Propagule Pressure and Less Intensive Disturbance

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Protected areas are established to conserve global biodiversity threatened by various factors, including invasive plants. We recorded naturalised alien plants inside and outside of protected areas to test whether they act as a barrier against the spread of alien plants.

Invasive species in protected areas of Croatia [PDF]

, 2018
Invazivne vrste su agresivne i brzo se rašire staništem. Na takvim staništima broj autohtonih vrsta se smanjuje zato što im invazivne vrste uzimaju prostor i hranu, a nekima su predatori. To dovodi do smanjenja biološke raznolikosti koja je uvelike važna
