Habitat Threats
Losses of Larvae or their failure to thrive
Predation
Predator Species
Forms of Prevention
Clues left of Predation
Disease (I assume there may be some)
Pollution (Originating from within Parks or External Sources and acting directly on the larvae or on things on which it depends)
Restricted Larval Habitat (Distress to individuals communities)
Loss of habitat size range due to removal of dead tree roots and the tidying away of dead trees in many areas adjacent to Richmond Park Wimbledon Common resulting in direct loss of habitat and to loss of soil, humidity and microclimatic diversity available in the area. We can think of this under general parameters or as specific needs and threats, some of which may be active in more than one of these parameters. Also there may be conflicting needs and or conflicting and combining threats that may be active in different parameters.
Extent Space - Key Indicators
Diversity of habitat - Key Indicators
Durability Long Term - Key Indicators
Consistency With Short Term Needs/ Location - Key Indicators
Specific Needs (e.g. Specific Fungi) - Key Indicators
Specific Threats (These are also discussed under some general headings such as Pollution) - Key Indicators
Losses of Adult too early
Restricted Emergence, Mating Laying Habitats that increase Predation other Losses of Adult Beetles prior to their contributing to breeding
Predators
Bird & Mammal Predation may be increasing due to large numbers of crows, magpies, etc. attracted to the site by the food and litter brought by people and left on the site.

Locally Restricted Genetic Diversity
either in Stag Beetle Population or in some of the soil fungi etc. on which it depends
Environmental Change Threats
Global Temperature Change - may affect the weather in this area so significantly reducing the range of available habitats and numbers of beetles they support
Man's Local Contribution
Pollution Threats
Fire Raisers
Encouraging predation Bird & Mammal Predation may be increasing due to large numbers of crows, magpies, etc. attracted to the site by the food and litter brought by people and left on the site. Observation that they left whilst Park was closed due to Foot & Mouth Outbreaks
Species Threats
Collectors
Tormentors
General Ignorance - Lack of public awareness and appreciation of the nature conservation importance of the habitats and of a species of European importance.
