as along roads, abandoned quarries, or on park boundaries. Significant weeds found in parts of the park are crofton weed (Ageratina adenophora), pine trees, and pampas grass (Cortaderia selloana), which is an easy proliferator. Many weeds are present outside the boundaries of the park, which present the threat of invasion. Some of these are gorse (Ulex europaeus), fireweed (Cotoneaster glycophylla), broad and narrow-leaf privet (Ligustrum spp.), Scotch thistle (Cirsium vulgare) and cassia (Senna pendula). In total, there are seven species of introduced mammals and four introduced bird species within the park. Foxes and feral dogs are a threat to koalas, and Feral cats and foxes are a real danger to many threatened species within the Upland Swamp region. Bats are especially vulnerable to feral cat predators. Feral cats, foxes and mosquito fish (Gambusia affinis) have been listed as creating key threatening processes (predation, competition and vegetation alteration) under the Threatened Species Conservation Act, 1995 (NSW). Chytrid fungus infecting frogs and feral deer causing environmental degradation (such as trampling and accelerating erosion), are also considered to cause threatening processes. Catchment The water extraction licenses issued in the park's catchment have the potential to reduce flow further down the catchment. Five weirs have been constructed within creeks in the park. These weirs exclude certain native fish from being able to reach creeks within the reserves, therefore preventing these fish from being able to complete their lifecycle. Mining Coal mining exploration has occurred in the park, which has caused cracking in creek beds as well as some damage to slopes and rocks. Stream flows have been altered due to cracking, which can lead to alterations in aquatic habitats and impacting on linked species. Cracking caused to the streams can be to such an extent as producing water loss. Management trails have previously been created using coal wash waste, which can be easily transported into the streams during rain events. This can cause alkaline conditions and can have a negative effect on flora and fauna. Fires Wildfires are a threat to flora and fauna within the park, and require fire protection and management, especially for areas such as core koala-breeding habitat. Threats of arson have also been made, both outside and within the park. Arson and accidental fires from bushwalkers have been the main reason for bushfires within the park. Management The park management is trying to protect and conserve the park’s natural and
