- n. any plant disease in which the central part of a plant rots (especially in trees)
Sorry, no etymologies found.
There is a different bias (Heartwood Rot Bias) in which, if an author assigns chronological year 1 to year 1 of a core with heartrot (which are presumably mostly subfossil), you make the subfossil trees date younger than they really are and bias your MWP/modern comparison.
For nesting, it looks for older pines that are infected with red heartrot, a fungal disease that softens the interior, making nest digging easier.
Their trunks become riddled with heartrot, and as their inner wood softens, tree-hugging conks erupt on their bark.
Be sure to check multiple-stemmed coppice trees for holes; they are particularly susceptible to heartrot.
Though their leaves may be slow to rot, the trunks of oaks are frequently stricken with heartrot.
Fires wound the base and trunks of forest trees severely so that they are exposed to serious destruction by heartrot.
