Pašne živali se hranijo z različnimi krmnimi rastlinami, da zadostijo svojim dnevnim potrebam po hrani, pri tem sledijo različnim prostorskim in časovnim vzorcem skozi leto. V raziskavi smo izbrali štiri različne črede ovac in koz (dve za vsako vrsto) in opazovali njihovo prostorsko razporeditev z ročnim GPS spomladi, poleti in jeseni. Istočasno smo tri živali v vsaki čredi neposredno opazovali pri paši. Podatke o času in natančno karto rabe tal smo obdelali v GIS-u, da smo dobili povezavo med aktivnostmi živali in različnimi krmnimi rastlinami. Ovce in koze so prehodile dolge razdalje (od 7,5 km do 9,0 km), da so v celotnem letu zadovoljile potrebe po hrani. Pasle so se na dveh glavnih tipih krme: pašnikih (travišča, grmišča in gozdni robovi) in kmetijskih površinah (prahe, strnišča in začasni pašniki). Obe vrsti sta se statistično značilno (P≤ 0.05) pasli krajši čas na pašnikih (38,9% in 18,1%) kot na kmetijskih površinah (63,6% in 53,4%) v spomladanskem in poletnem času. Očitno je, da je pestrost krajine nujna za ekstenzivne kmetijske sisteme z drobnico, saj se pašniki in kmetijske površine dopolnjujejo pri celoletni oskrbi s krmo.
