| description | Many carnivores outside protected areas are declining as they are being killed for their involvement in depredation on livestock. More knowledge of when and why predators leaves protected areas are key questions in mitigating the human-wildlife conflict. Ol Pejeta Conservancy, Kenya, holds the one of the country’s highest densities of predators, with approximately 100 spotted hyenas (Crocuta crocuta). Ol Pejeta is therefore a suitable site to learn more about the activity pattern of predators inside protected areas by analyzing photos from camera traps. The aim of this survey is to investigate the spatial and temporal movement pattern of spotted hyena and correlate it with moon phase and precipitation. If changes in clan size and attacks on livestock correlates with the environmental factors will also be studied. The results from this study showed that spotted hyenas walked out of the reserve after sunset and arrived before sunrise. Activity was higher when moonlight was bright compared to medium illuminance. Rainfall that arrived 30 days before had a negative correlation with activity, meaning that if precipitation was low the activity was higher. Group size mostly consisted of one or two individuals and could not be direct correlated to clan size nor to any environmental factor. Spotted hyena have had seven attacks upon livestock during this one year survey and could not be correlated with any temporal nor abiotic factors. Precaution during nighttime is preferable as the spotted hyenas are leaving the reserve even though they show a stronger preference for wild prey than livestock. |

Många rovdjur utanför skyddade områden minskar i antal då de dödas på grund av deras inblandning av boskapsattacker. Mer kunskap om när och varför rovdjur lämnar skyddade områden är nyckelfrågor i hur konflikten mellan människa och vilt hanteras. I Kenya ligger Ol Pejeta Conservancy som har ett av landets högsta rovdjursdensitet och med cirka 100 fläcka hyenor (Crocuta crocuta). Ol Pejeta är därför en lämplig plats att lära sig mer om aktivitetsmönstret hos rovdjur inom skyddade områden genom att analysera bilder från kamerafällor. Målet med denna studie är att undersöka de rumsliga och temporära rörelsemönstren hos fläckig hyena och korrelera det med månfas och nederbörd. Om förändringar i klanstorleken eller boskapsattacker beror på miljömässiga faktorer kommer också att undersökas. Resultat från denna studie visar att fläckiga hyenor går ut ur reservatet efter solnedgång och kommer tillbaka innan soluppgång. Aktiviteten var högre när månljuset var starkt jämfört med när månen lyste mellan ny- och fullmåne. Regn som kom 30 dagar innan hade en negativ korrelation med aktivitet, dvs att när regnfall var lågt så var aktiviteten högre. Gruppstorleken bestod mest utav en eller två individer och kunde inte direkt kopplas till klanstorleken eller med någon miljömässig faktor. Fläckiga hyenor har haft sju attacker på boskap under denna ettåriga studie och kunde varken kopplas till temporära eller abiotiska faktorer. Försiktighetsåtgärder under nattetid är föredraget då den fläckiga hyenan lämnar reservaten även om de visar en större preferens för vilt än boskap.
