Introduction - Historically, ecological research was conducted in pristine wilderness areas
- It is estimated that between 1/3 and ½ the planet’s land surface has been directly affected by humans
- Understanding the effects of human disturbance on ecosystem production is vital, especially in light of current concerns over global climate change and carbon budgets

2. Fertile Land Trend
In California, 15% of Fertile Agricultural Land is Urbanized (Imhoff Et al. 2004)

Discussion
What about…
- Root Biomass?
- Edge Effects?
How to address land mosaics?

Conclusion
Where to go from here?
- Continued integration of GIS, remote sensing, modeling, and field observation - Further refinement of current models
- Application to global climate change
