Welcome to Dr. Karen Holl's Research Website

Research in Dr. Holl’s lab focuses on understanding factors limiting recovery of ecosystems from human-induced disturbance and using this information to design restoration strategies.  Members of the Holl lab work in a range of ecosystems in California and in Latin America.  Lab members work closely with land owners and conservation organizations to exchange information about ecosystem restoration, and aim to apply the results of their research to land management and policy decisions.

NEWS 
I am thrilled to announce that my lab has just published a public Global Reforestation Organization Directory in collaboration with Mongabay. We score how well 128 global tree-growing organizations commit to following permanence, ecological, social, and financial best practices. Our goal with this site is to: (i) help potential funders identify organizations that share similar priorities and commit to the highest standards in reforestation efforts, and (ii) incentivize reforestation organizations to more clearly communicate their policies and develop more transparent reporting and data sharing practices. Read the Mongabay article about the new Reforestation Directory here

A few of our latest papers:

Pedro Brancalion and I published a paper about his spatially-patterned planting study in Brazil - Effectiveness of spatially patterned methods to restore semideciduous tropical forest

Brook Constantz led a paper in Restoration Ecology comparing habitat heterogeneity in restored and reference riparian forests along the Sacramento River.

Francis Joyce led a paper in Journal of Applied Ecology comparing seedling establishment limitation in our long-term restoration treatments in southern Costa Rica.

Dr. Holl's book "Primer of Ecological Restoration" is available in Chinese and Persian. The Spanish and Portuguese versions are available open access.
