Лесной дом: кто живёт в старых деревьях?

Derevʹi͡a ochishchai͡ut vozdukh, proizvodi͡at kislorod i pogloshchai͡ut uglekislyĭ gaz, vyzyvai͡ushchiĭ poteplenie klimata. Oni sberegai͡ut vodu v pochve i zashchishchai͡ut eë ot ėrozii. Oni delai͡ut klimat bolee vlazhnym i mi͡agkim, sglazhivai͡a kolebanii͡a temperatury. A samoe glavnoe dli͡a lesa - derevʹi͡a nezamenimy kak sreda obitanii͡a, vedʹ za svoi͡u dolgui͡u zhiznʹ oni dai͡ut pishchu i krov samym raznym zhivotnym: ot zhukov-oleneĭ do chërnykh aistov, ot bobrov do letuchikh mysheĭ. My uznaem, kto zhivët u reki, kakie sekrety tait bukovyĭ les, chto delaet dubravy osobennymi, i zagli͡anem vo fruktovyĭ sad i na gornyĭ sklon. I vezde v starykh derevʹi͡akh zhiznʹ prosto kishit!

Trees purify the air, produce oxygen, and absorb carbon dioxide, which causes climate warming. They conserve water in the soil and protect it from erosion. They make the climate more humid and mild, smoothing out temperature fluctuations. And the most important thing for forests is that trees are indispensable as a habitat, because over their long lives they provide food and shelter to a wide variety of animals: from deer beetles to black storks, from beavers to bats. We will find out who lives by the river, what secrets the beech forest holds, what makes the oak forests special, and take a look at the orchard and the mountainside. And everywhere in the old trees, life is just teeming!
