V poslednie desyatiletiya vo mnogih stranah mira nablyudaetsya massovoe usyhanie elovyh nasazhdeniy. El' - tenevynoslivaya drevesnaya poroda, dlya kotoroy dlya aktivnoy zhiznedeyatel'nosti polnota 0,8 yavlyaetsya optimal'noy. Nizkie polnoty mogut okazyvat' neblagopriyatnoe vliyanie na sanitarnoe sostoyanie derev'ev eli. Cel' issledovaniy - ustanovlenie vliyaniya polnoty elovyh drevostoev na ih ustoychivost' v zone hvoyno-shirokolistvennyh (smeshannyh) lesov Permskogo kraya. Ob'ektom izucheniya yavilis' smeshannye po sostavu elovye drevostoi III-VI klassov vozrasta Osinskogo i Chaykovskogo lesnichestv, raspolozhennye v zone hvoyno-shirokolistvennyh (smeshannyh) lesov Permskogo kraya. Proanalizirovany akty lesopatologicheskih obsledovaniy 2017 goda, zafiksirovavshie usyhanie eli. V 2017 godu v Osinskom i Chaykovskom lesnichestvah v drevostoyah III-VI klassov vozrasta otmecheno usyhanie eli v 185 lesnyh vydelah na ploschadi 1900,2 ga. Srednevzveshennaya kategoriya sanitarnogo sostoyaniya el'nikov Prikam'ya var'iruet ot 2,65 (sil'no oslablennye nasazhdeniya) do 4,22 (usyhayuschie nasazhdeniya). S uvelicheniem vozrasta sanitarnoe sostoyanie nasazhdeniya uhudshaetsya. S uvelicheniem polnoty nasazhdeniya srednevzveshennaya velichina sanitarnogo sostoyaniya umen'shaetsya, chto podtverzhdaetsya vysokimi koefficientami korrelyacii. Zapas suhostoya v el'nikah Chaykovskogo i Osinskogo lesnichestv var'iruet ot 20,5 do 59,5%. Naibol'shiy ob'em suhostoya (59,5 %) opredelen v nasazhdeniyah 5 klassa vozrasta. S uvelicheniem polnoty zapas suhostoya umen'shaetsya (ot 41,0 do 28,7 %). Vliyanie polnoty na sanitarnoe sostoyanie el'nikov sleduet uchityvat' pri naznachenii sanitarnyh i vyborochnyh rubok, a takzhe rubok uhoda
