A recent post by the New York Times said “When some plants are dehydrated or under some other form of stress, they cry a mournful melody made of ultrasonic clicks” referring to some new research that collected sounds from stressed plants. CBS News reported that, “Plants emit a “rather noisy” cry for help when under … Read More

Evaluated tower, mast, crane, and UAV methods for forest vertical gap fraction, LAI, and CI measurements in different seasons. UAV is promising for forest vertical structural profiling.
The vertical distribution of canopy structural parameters, such as canopy gap fraction, leaf area index (LAI) and clumping index (CI), is important for understanding the forest structural and functional properties. However, vertically distributed canopy structural data are rare, and current methods are either inefficient or costly for obtaining sufficient amounts of such data. This study conducted a series of field campaigns to obtain forest vertical structural measurements at two temperate forest sites in northern China from 2020 to 2023. Four different measurement systems were compared: (1) flux towers with accessible platforms at different heights, (2) a portable and extensible sampling mast with a digital hemispherical photography (DHP) camera attached on top, (3) a tower crane with a DHP camera fixed on the crane hook, and (4) an uncrewed aerial vehicle (UAV) with a DHP camera attached on top. The measured effective plant area index (PAIeff) shows clearly seasonal variations at different heights. The CI remains relatively consistent at different heights, and the leaf-off value is approximately 0.1−0.2 higher than the leaf-on one. The flux tower method can be used for vertical profile measurement at a fixed location, whereas the portable mast is suitable for lower-level (< 15 m) measurement. Crane measurement requires an established facility and is useful for local measurement around the crane. UAV with an attached DHP provides a promising method for monitoring vertical structural parameters. The vertical structural profiles obtained in this study can be used in various modeling and validation studies.
Hei, we are considering buying a little property (not our final home) close to a river which possibly can rise up to about 7 meters (23 feet).
We have not being on site yet and I’d like some info on how to calculate where the water line would be in case of worst case flom scenario. We have a map made from the a state Department and it seems that all of the property would get flooded. I want to learn how to calculate up to which level of the house and the barn the water could get.
Thanks 🌱

I have access to a good amount of fallen palm branches and am wondering if there are any good resources for using them as a construction material or other uses. I gathered a bunch after some heavy winds last night, planning to use the fronds for mulching or weaving and the branches for garden building materials: stakes, lattice, support, etc.
I’m wondering if there are other common uses I might be overlooking, especially for the reddish-brown curvy part that connects to the trunk. Is there anything practical to do with this part or should I just put it straight into the city compost bin?

US Fish and Wildlife Service extends protections to ‘iconic’ insects, who experts say may not survive climate crisis
The US Fish and Wildlife Service announced a decision on Tuesday to extend federal protections to monarch butterflies after years of warnings from environmentalists that populations are shrinking and the beloved pollinator may not survive the climate crisis.
Officials plans to add the butterfly to the threatened species list by the end of next year following an extensive public comment period.

Overview Description Onions are biennial plants, typically grown as annuals, primarily for their edible bulbs and green shoots. In their first year of growth, onions form a basal rosette of long, cylindrical leaves and develop a bulb underground. The plant’s leaves are hollow, tapering, and […]
