“…Mismatch of selection likely creates a trade-off where organisms select for less optimal habitat in order to provide protection (Crowder and Cooper 1982;Brown 1999;Ofstad et al 2020). Our results support previous results that cover is selected for at a greater rate than areas without cover when risk is high (Creel et al 2005;Drimaj et al 2021), and that habitat shift from risk can be a form of cover-seeking behaviour (Creel and Winnie 2005).…”

“…Food plots provide high-quality forage (Keegan et al . 1989; Hehman and Fulbright 1997; Edwards et al . 2004) while simultaneously being the most hunted areas in our landscape and increasing hunter success (Johnson and Dancak 1993).…”

“…Past studies have shown that large ungulates use different habitat during high-risk periods (Creel et al 2005;Drimaj et al 2021), particularly when that risk is from human hunters (Lone et al 2015;Ranglack et al 2017). However, the knowledge of risk effects on white-tailed deer (hereafter deer) is largely restricted to difference at a broad spatial scale (Karns et al 2012;Little et al 2016;Henderson et al 2020) rather than differences in habitat use.…”

Temporal effects of relative hunter activity on adult male white-tailed deer habitat use

Context Predation risk, whether from large carnivores or humans, is a primary driver of movement and habitat selection for ungulates. Throughout much of the geographical range of white-tailed deer, predation risk during autumn and winter is driven by hunters; however, information about how deer respond to hunting pressure during a long hunting season is lacking. Aims We aimed to determine how differences in daily temporal exposure to hunting risk affected habitat selection of adult male white-tailed deer. Methods We deployed GPS collars on 42 adult male white-tailed deer during the 2017–2018 and 2018–2019 firearm hunting seasons in Mississippi, USA. GPS collars provided fine-scale spatial and temporal information regarding habitat use of our study area. Key results We showed a mismatch between what hunters and deer selected; landscape characteristics selected most by hunters were least selected by deer during the day, which we believe has never been documented. Fine-scale temporal analysis showed that deer selected for some areas (food plots) as much as five times more often during the night, when no hunting risk was present, than during the day, when risk was present. Conclusions Habitat selection by deer varies depending on the amount of risk that is present. Even in a high-risk heavily hunted area, adult male white-tailed deer can recognise external cues on the landscape, and shift habitat selection both spatially and temporally to favour areas that present less risk. Implications This study, to our knowledge, provides the first evidence that white-tailed deer actively selected for habitat characteristics that hunters were not utilising. To minimise the effectiveness of risk-avoidance behaviours used by deer, we suggest hunters moderate temporal hunting effort across time to decrease the risk to which deer are exposed, thereby minimising the response by deer.

“…Forest habitats constitute a refuge for wild boars during the day when they avoid contact with humans [43]. For this reason, this habitat is constantly visited by wild boars [51,52]; therefore, as shown in our study, the forest habitat is preferred regardless of the stage of the summer period. It is true that wild boars can stay in arable fields around the clock, but this applies to areas with large-scale agricultural crops where there is not much forest habitat [43].…”

“…It is true that wild boars can stay in arable fields around the clock, but this applies to areas with large-scale agricultural crops where there is not much forest habitat [43]. Many researchers indicate that an important factor determining the composition of the wild boar's diet is the availability of forest tree seeds, such as acorns, chestnuts or beechnuts [52,53]. High availability of forest fruits is preferred in relation to agricultural crops, even maize, and to food supplied at feeding sites [54,55].…”

Crop Harvesting Can Affect Habitat Selection of Wild Boar (Sus scrofa)

et al. 2022

One of the basics of effectively managing a wild boar population is knowledge of its home range, spatial patterns, and habitat use. However, little is known about the reaction of wild boar to changes in the agricultural landscape during the time of harvesting. In this study, we assessed the impact of crop harvesting on habitat selection of wild boar. For this reason, we analyzed radio-collared animals in four summer months (from June to September) in an agricultural landscape in Poland. We analyzed the habitat selection by wild boar with a generalized linear model and Jacob’s selectivity index. The wild boar preference for arable land, pastures and the “other” category showed clear monthly dynamics. In contrast, a stable preference for forests and mosaics was observed throughout all months. The preference of wild boar to arable land dropped significantly in August, which we interpret as the impact of the harvest. We conclude that intensive agriculture contributes to significant changes in the frequency of wild boar in various habitats. This, however, does not apply to all habitats, because forest habitats are constantly visited by wild boar as their main daytime refuge. Moreover, extensive farming, although less attractive for wild boar, is rather neutral and does not alter the abundance of animals in habitats.
