Work done by the Caprinae Specialist Group of IUCN during 2024 and beginning of 2025
The escape and establishment of Iberian wild goats, Capra pyrenaica, from an enclosure in the 1990s marked the beginning of the recovery of the species in the Pyrenees. This population has occupied part of the Prepyrenees and has contacted another population reintroduced in France since 2014. It coexists with other wild ungulates, including the fer...
Hunting is one of the oldest and most relevant extractive activities performed by humans in nature. Over the last century hunting has experienced profound changes in developed countries, shifting from a consumption to a recreational activity and declining in some countries. However, substantial quantitative information on these trends at large temp...

Wild boar is an important species throughout the Iberian Peninsula, and populations exist from sea level to elevations of >2000 m in high mountain environments, which reflects its incredible ability to adapt to a wide range of natural and cultural environments. To summarize the scientific and management knowledge on this species in Portugal and Spa...
Trophy Hunting (TH) is thought to be the reason for the reduction in length and thickness of trophies as well as body size in several Bovidae species. In deer populations, changes have occurred in allele frequencies and in number of antler tips, possibly the result of the removal of males that showed the best trophies. To evaluate whether TH select...

In January 2000, the last Pyrenean wild goat, Capra pyrenaica pyrenaica, died in Ordesa National Park in the Spanish Pyrenees. Since that time, there has been an intense debate over the possibility of using individuals from other extant subspecies to restore the Iberian wild goat C. pyrenaica in the Pyrenees. In the late 1990s, some Iberian wild go...
To estimate the number and density of feral goats Capra hircus in Guara Nature Park (Pyrenees, Spain), 27 observation points were established throughout a 440 km2 portion of the park occupied by goats. In April and May 2009, goats were counted daily during 3-h observation periods that began at dawn. The counts documented 282 goats in 39 groups. The...
Between 2006 and 2008, an outbreak of Infectious Keratoconjunctivitis (IKC) affected Pyrenean chamois Rupicapra p. pyrenaica, an endemic subspecies of mountain ungulate that lives in the Pyrenees. The study focused on 14 mountain massifs (180,000 ha) where the species' population is stable. Cases of IKC were detected in ten of the massifs and, in f...
In Spain, Game Reserves (GR) are territorial public hunting management units that cover 3.5% of the country and similar to 10% of the Natura 2000 Network. The first GR were established in 1966 and by 2011 there were 49. Their primary purposes were to promote wild ungulate populations, their sustainable use, and to provide social, economic, and recr...
1. The introduction of non-native species can pose environmental and economic risks, but under some conditions, introductions can serve conservation or recre- ational objectives. To minimize risks, introductions should be conducted following the International Union for Conservation of Nature’s guidelines and should include an initial assessment and...
The remarkable increase of wild ungulates populations in Aragon during the last 50 years, both in numbers and distribution, has made population monitoring a need for effective management of these species. In parallel to their raising numbers, problems related to crop damage and collisions with vehicles are growing. In this situation there has been...
This study compared the efficacies of total block counts (BC) and distance sampling (DS) procedures to estimate the abundance of chamois populations in two mountain massifs, Posets and Maladeta, Spain. In 2002, 2006, 2007, and 2008, chamois populations were surveyed along itineraries above the timberline, twice per year: in July, after the parturit...
Although brown bears (Ursus arctos) are known to be major predators of ungulates in North America and Northern Europe, there is little documentation regarding
bear predation on wild ungulates in Southern Europe. We describe search, detection, killing and prey consumption behaviour
by brown bears during seven attacks on <1-month roe deer, red deer a...
The general human population trend in Ordesa and Monte Perdido National Park (OMPNP) during the
second half of the XX century has been its migration from the villages to the big nearest industrialized
cities. Consequently, livestock pressure declined, leading to the invasion of woody species into the
grasslands. Nevertheless, if grasslands have not...
Our research into the Cantabrian brown bear (Ursus arctos) has focused on females with cubs. Monitoring over the last twenty five years has provided data on demographic and spatial trends that are essential to conservation strategies and has also involved surveillance and protection.
Between 1988 and mid-2010 we observed 141 groups of females with...

From 1990 to 2006, we studied the demographic, reproductive, and biometric characteristics of two Iberian wild boarSus scrofa (Linnaeus, 1758) populations in contrasting environments. In the Pyrenees (studied in 1990–1993), forest cover is high, hunting
pressure is low, and the density of wild boar is high. In the Ebro Valley (studied in 1994–2006)...
A population of wild boars (Sus scrofa) became established during the 1990s in the Natural Park of Aiguamolls de l’Empordà, a wetland on the western coast of the
Mediterranean Sea (Catalonia, Spain). Between 2001 and 2004, a culling program was conducted to reduce the boar population.
We collected and analyzed the contents of 142 stomachs to charac...
We studied the diet composition and selection of plants in the Alpine marmot Marmota m. marmota of two family groups in the Western Pyrenees from May to September. The food consumed was determined by faecal analysis, and the plant selection was determined comparing the plant composition in faeces and plant availability in the area surrounding the m...
Major histocompatibility complex class II locus DRB variation was investigated by single-strand conformation polymorphism analysis and sequence analysis in the two subspecies of Pyrenean chamois (Rupicapra pyrenaica) endemic to the Iberian Peninsula. Low levels of genetic variation were detected in both subspecies, with seven different alleles in R...
The Middle Ebro Valley (MEV) is a semiarid area in northeast Iberia where the original riparian ecosystems are almost extinct
and were replaced by intensive irrigated agricultural lands. To minimize crop damages and to understand the impact of wild
boar on relict riparian ecosystems, a culling program was undertaken from 1994 until 2004. To assess...
