cool fires forestr.

[Касандрас]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте:
Thanks to their expertise in setting relatively cool, frequent fires, they lived surrounded by open, park-line forests of stately, well-spaced, old- growth ponderosa pine. A big ponderosa's thick bark withstands the cool fires that conveniently leave behind them a charcoal ring to mark their passing.

Read this, too:
Thus, a cool fire should be planned in an oak woodland if one does not know how the seedlings and saplings may respond.
Насколько я понял и помню из истории древлян, ими использовался, по-моему, подсечно-огневой метод для улучшения как плодородия земли, так и состояния лесов. Примеры, и Ваш, и мой - тому доказательство. Только у этого метода есть свой какой-то термин, которого я не знаю. Сейчас придут спецы и поправят меня или дадут термин.

Остались ещё в Калифорнии древние индейцы, которые "улучшают" свою землю огневым методом. Вот откуда пожары в Калифорнии!
Oak woodlands have burned for thousands of years. Native people burned the oak woodlands throughout California for many reasons. Often their fires were purposeful and directed to manage particular species. Certainly lightning fires in the coastal oak woodlands and those along the Sierra Nevada were common, and could burn for hundreds of miles if conditions were right. With the arrival of Europeans, fires were suppressed. After 200 years of fire suppression, and with warmer summer temperatures and drier years, fires have become frequent and large in California woodlands.
Oaks in California have been able to live with fire.Fire can kill the tops of seedlings and sapling. But mature trees are resistant to the quick heat of a grassland fire underneath them. They may look dead, but often in a year or so, the branches sprout new leaves. Saplings and seedlings sprout again the first year after a fire, and even first-year seedlings can resprout. These sprouts can grow far faster than the original seedlings, and so can often grow up and past the cattle and deer "browse line". In some places, especially where a stand of mature blue oak all appear to be of the same age, they may have been the result of a fire. In other places, blue oak recover poorly, if at all from fire. This seems to vary with genetic background. Thus, a cool fire should be planned in an oak woodland if one does not know how the seedlings and saplings may respond.
Очень похоже на того партизана из пинских болот, который пускал под откос составы, не ведая, что война давно закончилась...
