Near Remote Sensing to Track Changes in Phenology in Forests

Near Remote Sensing to Track Changes in Phenology in Forests | Plant Pest Modeling | Scoop.it

This year, the Richardson Lab of Harvard University and the Friedl lab of Boston University set out to study climate change using two different methods, remote sensing and near remote sensing in phenology of forests.


Phenology is the study of life cycles in various organisms. Specifically, we’ve been looking at tree phenology, tracking spring leaf out (when the trees start growing leaves after lying dormant all winter) and autumn senescence (when the leaves begin to change colors and drop from the trees). This summer, we have had the opportunity to challenge the question “Can webcam imagery track phenological changes?”

Observe Plants and Animals | USA National Phenology Network | Plant Pest Modeling | Scoop.it

Welcome to Nature's Notebook, a national plant and animal phenology observation program. You can join thousands of other individuals who are providing valuable observations that scientists, educators, policy makers, and resource managers are using to understand how plants and animals are responding to climate change and other environmental changes. Observations by participants like you are already helping researchers detect early leaf-out in forests from St. Louis to Maine in response to unusually warm winters and springs

The USA National Phenology Network is Up and Running

Continental-scale monitoring is vital for understanding and adapting to temporal changes in seasonal climate and associated phenological responses. The success of monitoring programs will depend on recruiting, retaining, and managing members of the public to routinely collect phenological observations according to standardized protocols. Here, we trace the development of infrastructure for phenological monitoring in the US, culminating in the USA National Phenology Network, a program that engages scientists and volunteers.

D.C. cherry trees: Blooms won't wait in warming world, research finds | Plant Pest Modeling | Scoop.it

Plant phenology models that consider when plants bloom and bear fruit in response to temperature are used for agricultural crops such as apples and grapes.

 

This type of predictive model will become increasingly useful when it is capable of making real-time forecasts," the authors wrote. For fruit crop production, for example, plant-growth models might someday help predict flowering dates so farmers know when to arrange with bee handlers to have their apple, pear, peach trees and other deciduous fruit trees pollinated as well as optimize the use of resources with minimal environmental impacts.

More Phenology - Wayne 

Yesterday I mentioned that the extremely warm March (coupled with all three winter months being warmer than average) had galvanized my reexamination of timings of flowerings and emergences of spring plants. Some of these go back to 2004 or 2005. Because this year is so extreme, I’ve looked at previous years' observations and have determined a midpoint based on blog entries and photographs.
