Non-native trees decline as tropical forest canopies return

Young tropical forests show many non-native trees while canopies remain open. As forests mature and canopies close, these non-native species tend to decrease. This pattern was observed across ten tropical countries in a recent study. Early forest regeneration is vulnerable to invasive species, which can establish easil

Deer are hollowing out forests of food sources which support forest ecosystems, according to a paper by the University of Canterbury published today.
