Help Track the Health of Redwood Forests

In 2008, League scientist Emily Burns discovered that the height of the most common plant in the coast redwood forest is affected by how much rain and fog fall in the woods. Western sword fern (Polystichum munitum) has tall fronds in wet redwood forests and much shorter fronds in dry forests. For this reason, sword fern is an important indicator of climate change and we are studying these ferns to detect drought in the redwood forest.
