A short 🧵 follows...
Spectral recovery=# of yrs reqd for pixel to attain 80% of its pre-disturbance NBR value (Years to Recovery, Y2R). NBR=Normalized Burn Ratio, which exploits differences in spectral response of vegetation & exposed soil in NIR and SWIR wavelengths. Enabled by #Landsat time series.

#Lidar is an operational technology for #forestinventory. Single-photon lidar (#SPL) may provide an acquisition advantage for large areas. How does #SPL perform in an area-based #forest inventory? Some things we have learned (i.e. a thread)!
#OpenAccess: bit.ly/37GTeZG2/ We used #SPL and 269 field plots to generate an area-based operational #forestinventory over a 15000 ha study area of temperate mixedwood forest representing a complex assemblage of tree species, forest structures, and management histories. bit.ly/37GTeZG

An increasingly common question: “We generated an enhanced forest inventory with #lidar data and ground plots for one of our management units. Can we use the same models for our other management areas?” #CFSEFI#forestinventory
A great question and one that is top of mind for many of us who generate and use #forestinventory data. So what does the #science tell us about the transferability of area-based models? #CFSEFI
