Slightly feral, interested in all things hyperborean, plus megafaunal extinctions.
Yukon bison herd makes a big dent in snow pack while grazing grass along bottom valleys that are too wet in the summer to graze. The stomp and rub smaller spruce trees, and add significantly more manure and nutrients to the system, changing grass into higher density fertilizer.

A grizzly bear versus a short faced bear, both bones found in the Yukon. Crazy to think our landscape supported 1000kg bears until very recently. As per Wikipedia dense forests occurred at the same time as these omnivores went extinct.

Here is 3 summers of growth after thinning a very dense 55 year old stand east of Prince George. The original stand was about 5000sph and had moss only as understorey with odd cornus canadensis.

If only Asian elephants could just grow some hair and move north.

First record of the spotted hyena Crocuta crocuta in Egypt during the past 5,000 years
An individual of spotted hyena Crocuta crocuta was killed by local people in Elba Protected Area, South-East Egypt in winter of 2024. This record constitutes the first record of the species in contemp...

Most forests have grown too thick for optimum biodiversity. This is what we should do to fix that, balancing fire hazard, biodiversity, human needs and a climate resilient forest. Mimicking mastodons is much more appropriate than mimicking large fires which are unnatural in evolutionary time scale
