This is an indicative distribution map of the present distribution of the species based on best available knowledge. See map caveat for more information.
The Peninsula Eyebright is a short-lived perennial herb, usually less than 35 cm high. Three types are recognised: Type 1 is generally larger, with a yellow green appearance and mauve, partially striated flowers, Type 3 has a reddish green appearance and white flowers that are not always striated and Type 2 tends to be intermediate with either white or mauve flowers (Threatened Species Unit 1997a).
Type 2 plants at Hurricane Heath generally grow no more than 12 cm high (Threatened Species Unit 1997a).
The four extant populations are restricted to the eastern side of Tasman Peninsula, eastern Tas. They have a linear range of 21 km and occupy less than 10 ha. The species once extended as far as Forcett near Sorell and near Stormlea in the SW part of Tasman Peninsula. The species may exist in other areas of the Tasman Peninsula, on Forestier Peninsula and beyond (Threatened Species Unit 1997a). There is one population of Type 1, two of Type 2 and one of Type 3.
Type 1 occurs on the northern edge of the Tasman Peninsula, partly within State Forest. The population is now restricted to three patches in a 2.5 km stretch behind Taranna (Threatened Species Unit 1997a). In 1995 one patch was estimated to contain 100-250 plants. Half the patch was destroyed in 1996 (Potts 1997 in Threatened Species Unit 1997a). Another patch occurs on the edges of a 4WD track through a State Forest coupe clearfelled and burnt in 1984. The third patch is along old 4WD tracks on the boundary of State Forest (Threatened Species Unit 1997a). The total number of Type 1 plants was estimated as 120-700 (Comm. of Aust. 1999d).
Type 2 occurs in at least four discrete patches (Comm. of Aust. 1999d) along a 2.2 km stretch of the Cape Hauy Peninsula, on the SE part of Tasman Peninsula. Another Type 2 population occurs at Hurricane Heath on Cape Pillar (Threatened Species Unit 1997a). The Cape Hauy Peninsula plants tend to occur along track edges. Hurricane Heath plants are concentrated in relatively bare patches created by temporary watercourses in very exposed heath (Comm. of Aust. 1999d). In 1995 approximately 350 Type 2 plants were located on Cape Hauy (Threatened Species Unit 1997a), increasing to 600 in 1996 following an unusually wet spring and summer, though the range did not increase (Potts 1997 in Threatened Species Unit 1997a). Numbers at Hurricane Heath were estimated to be 1000-2500 (Threatened Species Unit 1997a). The total number of Type 2 plants was estimated as 1630-8450 (Comm. of Aust. 1999d).
Type 3 occurs along the edges of a dirt road in a State Forest coupe on Arthurs Peak, behind Eaglehawk Neck on Tasman Peninsula (Threatened Species Unit 1997a; Comm. of Aust. 1999d). The Type was initially widespread throughout the coupe after clearfelling and burning, but ten years later was restricted to the edges of Plateau Rd running through the coupe (Threatened Species Unit 1997a). In 1995 approximately 1300 individuals, including 800 mature plants, were estimated in the Type 3 population. In 1996 numbers increased to 2000 following an unusually wet spring and summer, though the range did not increase (Potts 1997 in Threatened Species Unit 1997a). The total number of individuals was estimated at 3000-5000 individuals (Comm. of Aust. 1999d).
Continuous stands are likely to be formed after a fire event, joining the small remnant patches evident in the mid 1990s (Threatened Species Unit 1997a).
The two Type 2 populations occur in Abel Tasman Forest Reserve and Cape Pillar State Reserve. Types 1 and 3 are unreserved (Threatened Species Unit 1997a). The species has also been recorded from Point Puer-Crescent Bay State Reserve and Tasman Arch State Reserve (Briggs & Leigh 1996).
Suitable habitat for this species is heathy, sedgey or grassy open woodland areas (Threatened Species Unit 1997a), also described as moorland (Comm. of Aust. 1999d), often at forest margins.
Type 1 plants occur in open woodland with a heath and sometimes sedge understorey, especially along the edge of animal and 4WD tracks. Type 3 plants occurred throughout a coupe that was clearfelled and burnt in 1987, but ten years later were restricted to the heathy edges of a road running through the coupe. Type 2 plants occur in heath, with the Hurricane Heath population in very low, very exposed and wet heath (Threatened Species Unit 1997a).
Populations of Euphrasia species are transient. The persistence of populations is reliant upon the successful recruitment of seedlings. Patches of open ground are required for germination, and adequate moisture levels are required for seedling survival. Seed production is copious and the soil seed bank probably survives for decades (Potts 1999). Standing plants are killed by fire (Comm. of Aust. 1999d), but profuse germination follows (Potts 1999).
Euphrasia species are non-host specific semi-parasites. The growth rate and reproductive output is reduced in the absence of hosts (Potts 1999).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
