ForewordFriday: Understanding Fragmentation

By Chidinma Onuoha / On June 7th, 2019
Migrating wildlife species across the globe face a dire predicament as their traditional migratory routes are cut off by human encroachment. Forced into smaller and smaller patches of habitat, they must compete more aggressively for dwindling food resources and territory. This is more than just an unfortunate side effect of human progress. As key species populations dwindle, ecosystems are losing resilience and face collapse, and along with them, the ecosystem services we depend on. Healthy ecosystems need healthy wildlife populations. One possible answer?

Determining When Trees Are Drought Stressed

By Richard Waring / On February 18th, 2019
Unlike most annual crops, the roots of long-lived trees can penetrate through soils to great depth to reach water (Figure 1).  If we can’t tell how deeply roots penetrate, how do we determine when trees run out of water?  One way is to monitor the moisture status of leaves and twigs, because these are connected through the sapwood in branches, stems, and roots to water deep underground.

One dictionary definition of conservation I found defined it as the act of preserving, guarding, or protecting. But what does one guard or protect when gone is the certainty that even a particular habitat, species, park or preserve will remain viable in the relatively near future (next 100 or so years). What does that mean for how we conceive of conservation?
