“…Bottomland sites often contain sedges and other plants that have starchy roots and tubers, as well as mast-producing hardwoods. Bottomland sites and the waterways associated with them also serve as corridors that provide protection for swine as they travel to other desired vegetation and feeding locations like cropland fields (Franckowiak et al 2018; Friesenhahn et al 2023). The need for thermoregulation through wallowing (Graves 1984; Miller 2012) and proximity toward preferred foods (Schlichting et al 2015; Clontz et al 2021) likely make bottomland sites the preferred vegetation type in this region.…”

“…Measuring damage over time is another important gap because many types of damage are highly seasonal and thus the presence and impact of damage can change dramatically throughout the year. For example, for a crop such as corn, wild pigs may target the crop only immediately after planting (to consume seeds) or just before harvest (to consume ears of corn; Friesenhahn et al 2023). Thus it may be important to quantify damage immediately after these times because damage at different stages may be inapparent or have different value to producers, and estimating damage through total crop yield losses could be inaccurate as it could be attributed to multiple causes.…”

Damage assessments provide evidence for initiating and evaluating management programs that protect natural resources and human livelihoods against invasive species. Wild pigs (Sus scrofa) cause extensive damage in their native and non-native ranges, but the extent of current damage and efficacy of management of the damage (i.e., population control of wild pigs, exclusion fencing, etc.) remains poorly described. We conducted a systematic review of physical damage caused by wild pigs to summarize what is known and identify knowledge gaps for damage assessment. Wild pig damage assessments have been overwhelmingly qualitative (84% of studies) and measured differently across studies, which prevents the determination of typical damage amounts to a particular resource and comparison across studies. Key priorities going forward are to standardize damage assessments quantitatively and measure population density (or index of such) of wild pigs concurrently with damage assessments to determine the relationship between damage and population levels. We provide a framework for inferring damage in new areas and assessing the benefits of management—to evaluate and optimize landscape-scale management programs. Overall, we recommend future studies strive for: (1) report the amount of damages in a standardized fashion (e.g., area damaged/area surveyed), (2) evaluate and report the amount of damage relative to the density of wild pigs, and (3) when reporting economic costs of damages incurred and management actions, describe the economic valuation method used along with the year of reference for the valuation. Capturing these elements are necessary steps to predict the benefits of management for an area with particular profile of resources and wild pig density, even in areas where damage assessments are not available. Meeting these criteria with allow for more generalizable results that can inform managers across the nearly global distribution of wild pigs.

In Finland, the wild boar (Sus scrofa L.) lives on the northernmost edge of the species’ distribution range, and the population mainly originates from individuals immigrating from Russia. Most of the current population lives in the southeastern part of the country, and the wild boar is steadily expanding further. To develop effective risk and population management in novel northern wild boar regions, detailed information about the species’ local ecology is required. To estimate wild boar movement patterns, 17 adult wild boars were monitored using GPS collars from May 2020 to September 2022 in the core region of the current distribution. The average total home ranges of wild boars (87.1 ± 17 km2 MCP, 33 ± 5.5 SE km2 95% KDE) were larger compared with studies from southern latitudes. The length of nocturnal activity times varied seasonally. All studied individuals at the border zone (N = 15) showed continuous transboundary movements, with home range core areas located mainly on the Russian side. Wild boar locations were predominantly in the Russia border zone, especially resting sites during the daytime. Most locations in Finland were from night-time feeding excursions. Our study shows that, although home ranges are large, adult wild boars are relatively sedentary also in northern latitudes. However, the movement capacity of the species enables the transboundary spread of diseases such as African swine fever. Our results provide information for risk management and emphasize the importance of transboundary collaboration in the monitoring and management of common wild boar populations.
