“…The likelihood of a green turtle erroneously ingesting plastic debris, often by mistaking them for food, rose from 30% in 1985 to almost 50% in 2012 (Schuyler et al 2013). Human-induced rapid environmental change (HIREC, sensu Sih et al 2011) is filling animals' environments with new threats which bear little or excessive similarity to those they have encountered in their evolutionary history (Dwernychuk and Boag 1972;Patten and Kelley 2010;Witherington 1997). As a consequence, many of the stimuli involved fall outside the adaptive processing space of animals' evolutionary perceptual, learning, memory and decision-making systems, making individuals particularly vulnerable to their impact.…”

“…Although monitoring data collection is needed to confirm, this scenario is similar to the 'mega-trap' concept described by Kagan et al 15 , in which solar power developments act as an ecological trap as a result of the creation of favourable areas which offer reproductive and foraging advances within the surrounding ecosystem. 42 Exploring the impacts on fauna and habitat transformation in general combined with the feedback regarding the quality of biodiversity data sets used in the early stages of the EIA process justifies a clear concern, but it also creates a timeous opportunity. The timing in South Africa is ideal, considering that renewable energy developments are still in the early stages and there is a high potential to gain experience in these impacts.…”

According to recent national energy plans and policy documents, the number of renewable energy developments is expected to increase in South Africa, thus contributing to the diversification of the country’s energy system. Consequently, numerous solar power developments are being deployed in the sunny arid interior – areas generally represented by the Nama-Karoo and Savanna Biomes. These developments come with a range of novel environmental impacts, providing opportunities for multidimensional exploratory research. Here, a mixed-method approach was used to identify and investigate possible environmental impacts associated with two types of solar power plants: concentrating solar power and photovoltaic. Structured interviews conducted with experts and experienced professionals, together with observations from site visits generated complementary findings. In addition to the risk of cumulative ecological impacts associated with individual solar plant developments, landscape impacts of multiple power plants and the direct impact on avifauna were found to be the most significant environmental impacts. These direct impacts appear to be most significant during the construction stage, which represents an intensive 10% of the total power plant lifespan. This investigation provides an early, broad and informative perspective on the experienced and expected impacts of solar power in South African arid regions as well as insights to possible future research areas.

“…The ecological concept of a trap was proposed nearly half a century ago by Dwernychuk and Boag (1972), who suggested that this phenomenon may be common on the planet due to the considerable anthropogenic changes to the environment. One of the fundamental concepts is that an 'ecological trap' created by rapid anthropogenic change can facilitate extinction (Fletcher et al 2012).…”

Ecological and anthropogenic traps exist and exert a negative effect on Lapwing populations. We believe that an anthropogenic trap is a partial or delayed manifestation of an ecological trap. In recent decades Lapwing communities have shown higher affiliation with urban landscapes, which negatively influences breeding success and the overall density of the species. It appears that the Lapwing has fallen into an anthropogenic trap, which in Ukraine is represented by agricultural landscapes. The decline in the Lapwing population is mainly caused by high intensity of agriculture, overgrazing, desolation of agricultural lands, changes in the water regime of rivers and lakes, global forestation, increasing disturbance by recreational activity and tourism, and an increase in the distribution and number of predatory mammals. Controlled burns of dead vegetation performed in late spring, household waste disposal, and construction work all contribute to the loss of breeding grounds. As a result the majority of local Lapwing populations declined during last decade, and some populations have gone completely extinct.
