“…Interestingly, these regions are the stronghold of the wild pig population in the USA, 18,39 which are known to cause severe damage to agricultural crops. 40,41 Based on ground-based surveys of corn and peanut fields in South Carolina, the extent of forested and wetland areas surrounding crop fields was found to be the most important attributes positively associated with wild pig damage, whereas the amount of adjacent agricultural area and paved roads were associated negatively. 42 Future research should investigate the link between wildlife damage and wild pig presence.…”

BACKGROUND: Wildlife damage to crops is a persistent and costly problem for many farmers in the USA. Most existing estimates of crop damage have relied on direct assessment methods such as field studies conducted by trained biologists or surveys distributed to farmers. In this paper, we describe a new method of estimating wildlife damage that exploits federal crop insurance data. We focused our study on four crops: corn, soybean, wheat, and cotton, chosen because of their economic importance and their vulnerability to wildlife damage. RESULTS: We determined crop-raiding hot spots across the USA over the 2015-2019 period and identified the eastern and southern regions of the USA as being the most susceptible to wildlife damage. We estimated lower bounds for dollar and percent losses attributable to wildlife to these four crops. The combined loss across four crops was estimated at $592.6 million. The highest total estimated losses to wildlife were incurred by soybeans ($323.9 million) and corn ($194.0 million) and the highest percentage losses were estimated for soybeans (0.87%) and cotton (0.72%). CONCLUSION: We believe the proposed method is a reliable way to evaluate geographic and temporal heterogeneity in damages for the coming years. Accurate information on damages benefits various management agencies by allowing them to allocate management resources to crops and regions where the problem is relatively severe. A better understanding of damage heterogeneity can also help guide research and development of new management techniques.

“…Crop establishment is affected by five major groups of drivers and their interactions namely seed and seedling characteristics, seedbed components (physical, chemical and biological), weather, cropping systems (Lamichhane et al, 2018), and animal pests coming from outside the seedbed (Lamichhane et al, 2020b). The latter have been increasingly reported to cause post-emergence damage of field crops (Dimitri et al, 2012;Firake et al, 2016;Lamichhane, 2021;McKee et al, 2020;Nasu and Matsuda, 1976). A successful management of animal pests affecting crop establishment requires a systems-level approach that combines a range of disciplines including Agronomy, Biology and Ecology.…”

“…Nevertheless, these studies did not focus on evaluating post-emergence seedling losses due to biotic stresses in general and those due to vertebrate pests in particular, which were frequently observed across the experimental sites. Post-emergence seedling losses due to vertebrate pests represent an important problem for many field crops, leading to severe economic losses across the globe ( Firake, Behere & Chandra, 2016 ; Giunchi et al., 2012 ; McKee et al., 2020 ; Nasu & Matsuda, 1976 ).…”

The quality of field crop establishment is an indicator of the productivity and yield quality of a given crop. Several biotic and abiotic factors, as well as cropping practices, affect the quality of field crop establishment. More specifically to soybean, recent studies quantified pre-emergence seedling losses and identified the associated causes of non-emergence. However, little is known about post-emergence seedling damage, mainly due to vertebrate pests, which represent an important problem for growers. A 2-year field observation was conducted to quantify near- and post-emergence seedling damage due to vertebrate pests. The common wood pigeon (Columba palumbus) and the European hare (Lepus europaeus) were associated with this kind of damage. The characteristic damage due to the common wood pigeon consisted of either partially-damaged cotyledons during emergence or completely uprooted seedlings at emergence. In contrast, damage due to the European hare consisted of chewed seedling or seedling parts. There was significant effect of year (p < 0.001) on the final rates of post-emergence seedling damage due to the wood pigeon but not on those due to the European hare. The final rates of post-emergence damage due to the wood pigeon were higher (32% for 2018 and 22% for 2020) compared with those owing to the European hare (18% for 2018 and 17% for 2020). The severity of damage due to vertebrate pests was related to the type of seedling damage that, in turn, affected the capacity of soybean to compensate for post-emergence seedling damage.
