Every year since 1999, the PISCO team heads out to California's nearshore oceans and islands to monitor the health of kelp forests and evaluate the effectiveness of Marine Protected Areas.
Kelp forests are among the most unique and ecologically diverse ecosystems in coastal temperate oceans and are found globally. In the eastern Pacific ocean, they occur from Alaska and Canada to the waters of Baja California in the northern hemisphere, and along the southern coast of Chile in the southern hemisphere. Kelp forests need rocky coastlines where their holdfasts can take anchor, and cool (50 – 64 °F), clear, nutrient rich water to grow. These forests are tiered like a terrestrial rainforest with a canopy and several understory layers below.
PISCO’s kelp forest monitoring programs are designed to reveal geographic patterns of the structure and functions of this important ecosystem through quantification of the abundance of the macroalgae, invertebrates and fishes that constitute kelp forest communities. Our approach allows us to quantify large- and small-scale spatial patterns of structure of the kelp forest communities as well as characterize changes over time. This information provides insight into the causes and consequences of changes in species abundance resulting from natural and anthropogenic factors and as such forms the basis of ecosystem-based management of kelp forest communities.
