-Ingen har sagt att det finns f\u00e5 \u00e4lgar!<\/strong><\/p>\nS\u00f6kte och hittade lite siffror p\u00e5 n\u00e4tet, som sa att ett nuvarande revir i s\u00f6dra Sverige \u00e4r under 50 000ha och flera inte st\u00f6rre \u00e4n 20 000ha j\u00e4mf\u00f6rbart med 100 000ha i norra Sverige.
\nVargens f\u00f6da best\u00e5r till 80% av \u00e4lg och i ett revir d\u00f6das ca 80-100 \u00e4lgar per \u00e5r.
\nI exemplet nedan har jag r\u00e4knat med att ett vargrevir \u00e4ter 90 \u00e4lgar per \u00e5r.<\/p>\n
V\u00e5rt \u00e4lgsk\u00f6tselomr\u00e5de \u00e4r 22 000ha och vi har en tillv\u00e4xt p\u00e5 ca 50 \u00e4lgar och en avskjutning p\u00e5 ca 40 \u00e4lgar.
\nDet betyder att vi g\u00e5r ca +\/- 0 varje \u00e5r om vi \u00e4ven r\u00e4knar med trafikolyckor och h\u00e5ller v\u00e5r \u00e4lgstam.<\/p>\n
En varg \u00e4ter 8-9kg k\u00f6tt per dag.
\nJag delar upp 90 \u00e4lgar p\u00e5 50 kalvar x 40kg k\u00f6tt och 40 vuxna \u00e4lgar x 100kg k\u00f6tt, blir totalt ca 6000kg k\u00f6tt. 6000kg k\u00f6tt delat p\u00e5 365 dagar blir 16kg k\u00f6tt per dag.<\/p>\n
Vi har 7 \u00e4lgar\/1000ha (7 x 22) vilket betyder att det finns ca 154 \u00e4lgar<\/strong> i v\u00e5rt \u00e4lgsk\u00f6tselomr\u00e5de.
\nCa 50% av \u00e4lgarna \u00e4r kor vilket betyder ca 77 st.
\nEn \u00e4lgko har en reproduktion p\u00e5 0,65 vilket betyder att det varje \u00e5r f\u00f6ds 77 x 0,65= ca 50 kalvar.<\/p>\nDet borde betyda att vargen f\u00f6rsta \u00e5ret<\/strong> skulle minska \u00e4lgstammen (154+50-90) med ca 40 \u00e4lgar (utan jakt) och antalet \u00e4lg efter f\u00f6rsta \u00e5ret skulle vara 114 \u00e4lgar<\/strong>\u00a0( 5 st \u00e4lgar\/1000ha).<\/p>\nAndra \u00e5ret<\/strong> blir det p\u00e5 samma s\u00e4tt och det f\u00f6ds 37 kalvar och efter andra \u00e5ret \u00e4r antalet \u00e4lgar (utan jakt) 61 \u00e4lgar<\/strong> (2,7 st\/1000ha).<\/p>\nOm det finns 30 \u00e4lgkor kvar Tredje \u00e5ret, <\/strong>kan det f\u00f6das ca 20 kalvar och det blir d\u00e5 81 \u00e4lgar att \u00e4ta och vi hamnar p\u00e5 -9 \u00e4lgar<\/strong> (0 st\/1000ha).<\/p>\n![\"\"](\"https:\/\/blogg.atl.nu\/morteleks-fralsegard\/wp-content\/uploads\/sites\/43\/2023\/01\/varg.png\")

Nu \u00e4r fr\u00e5gan hur stor p\u00e5verkan vargen kommer att ha p\u00e5 \u00e4lgen och om \u00e4lgen kommer att bli en r\u00f6dlistad art, men med dagens jakttryck skulle jag inte s\u00e4ga att vi har f\u00e5 \u00e4lgar.
