The report identified two methods that provide reliable information and included guidance on how these techniques can be undertaken. The first approach involves night-time surveys, using either lamps or thermal imaging equipment and the second assesses mountain hare dung accumulation. The night-time surveys using lamps are the most simple and cost-effective method, a key aim and recommendation of the research. Daylight survey techniques were discounted as unlikely to provide a reliable or repeatable population index. Factors affecting climate". The United Kingdom Environmental Change Network. Archived from the original on 16 July 2011. Their results have been really fascinating. The hares switch from an almost purely nocturnal existence in the months between October to February to one involving much more daylight activity during the reproductive period between March and September. The results for March indicate that the three hour period from one hour before to two hours after sunrise contains an even pattern of activity and is therefore an appropriate time to count.

Alpine ecosystems can also thus be particularly climatically sensitive. Many mid-latitude mountains act as cold climate refugia, with the ecosystems occupying small environmental niches. As well as the direct influence that the change in climate can have on an ecosystem, there is also the indirect one on the soils from changes in stability and soil development.

[52] Everest is highest from sea level (green), Mauna Kea is highest from its base (orange), Cayambe is farthest from Earth's axis (pink) and Chimborazo is farthest from Earth's centre (blue) Climate in the mountains becomes colder at high elevations, due to an interaction between radiation and convection. Sunlight in the visible spectrum hits the ground and heats it. The ground then heats the air at the surface. If radiation were the only way to transfer heat from the ground to space, the greenhouse effect of gases in the atmosphere would keep the ground at roughly 333K (60°C; 140°F), and the temperature would decay exponentially with height.

Sewn into Mountain Equipment’s approach to outdoor gear, this grounded ethos guides the brand. Upheld by Matt and his colleagues, it connects strongly with Gore’s commitment to quality and durable performance.

There is no universally accepted definition of a mountain. Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain. [4] In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which, relatively to the adjacent elevation, is impressive or notable." [4] As an enthusiastic mountaineer with over 7 years of experience at Mountain Equipment, Matt stands by the need for simplicity and quality in products. Mountain Equipment and the GORE-TEX brand reflect this throughout their shared history. A heritage maintained today by innovators like Matt. But where did this all begin? How Mount Fuji became Japan's most sacred symbol". National Geographic. 6 February 2019. Archived from the original on 9 February 2019. A: Yes. Heather moorland that is managed for red grouse is a good habitat for mountain hares. This is probably because the predator control, combined with rotational burning that produces new heather growth, benefits both grouse and hares.Massimino et al. (2018) and Watson and Wilson (2018) – Both studies reported declines in mountain hare abundance indices. Significant population declines in 34% of the mountain hare’s British range occurred between 1995-2015. A 30% decline in abundance was found each year between 1999-2017 on moorland managed for grouse in eastern Scotland. However, an on-going analysis of GWCT hare data collected during grouse counts on the same estates surveyed by Watson and Wilson found no evidence to support these declines, and the analysis and conclusions used by Massimino have been challenged. A: Mountain hares are the only native lagomorph in Britain. They used to be found throughout the country, but when brown hares were introduced to England probably by the Romans, mountain hares became restricted to the upland regions. In 2017 the British army even performed a South Pole crossing using those very sleeping bags. Our innovative nature continued in 2018 when 10 mountain guides pushed the GORE-TEX Pro fabrics to the limit while surviving blistering Scottish weather for 6 months. PTES has been supporting Carlos Bedson’s work at Manchester Metropolitan University to work out which is the best way to accurately count hares. Mountain hares, the lesser-known cousin of brown hares, are on the very edge of their range in the UK. And the English population, found only in the Peak District, is small and very vulnerable to our changing climate. As well as being much loved icons of UK uplands, mountain hares are essential parts of these ecosystems. These herbivores feed on the vegetation, recycling nutrients as they go. They’re also an important prey species for raptors, owls, foxes, stoats and weasels.Knowing how many hares there are helps us to protect them more effectively, and to understand whether our methods are working. But what’s the best way to count hares?

The game box includes a four-piece game board, two cardboard 3D ‘mountain’ pieces which slot together and slot into the board, four playing pieces with plastic bases, a plastic piece for the mountain summit and 13 yeti footprints – ten with numbers between one and five, and three with yetis on the reverse.Searle, Michael P (2007).

(2019) – Count data gathered during red grouse surveys in the Scottish Highlands show that indicators of mountain hare abundance are up to 35 times higher and either relatively stable or increasing on driven grouse moors compared to moorland not managed for driven grouse shooting, where average declines were -40% per year in some areas.

To set up, pop out and discard the circles on the mountain to make holes for the players to hook their pieces into. Assemble the four-piece board and then the 3D mountain on top, ensuring that the colours match up. Pop the yeti feet out of the cardboard surround. My only thought was that it would be great if you could get more pieces with slightly higher numbers, or even perhaps a different colour indicating minus spaces, for more competent counters. A: The mountain hare is listed under Annex V of the EC Habitats Directive (92/43EEC) as a species “of community interest whose taking in the wild and exploitation may be subject to management measures”. As well, Article 14 of the Directive requires member states to ensure that the exploitation of such species “is compatible with their being maintained at a favourable conservation status”. This means that culling and recreation shooting of mountain hares is legal if it is proven to be sustainable. In Scotland there is an open season from 1 August – 28 February. Mountain hares are shot for recreation, disease control amongst red grouse and sometimes to protect newly planted woodland.A: This would depend on what land use replaced grouse shooting. Alternatives such as commercial forestry or possibly more intensive grazing may result in lower numbers. Research by the GWCT reported lower abundance indices and declines in areas where moorland habitats have become fragmented through afforestation, which has created upland landscapes less suitable for mountain hares.

Place the playing pieces inside their plastic bases (a coin can help with this so that the card doesn’t get bent) and then place the white piece on top of the mountain.
