Criteria for failure: The number of populations have decreased and/or the number of mature individuals have decreased by ten percent or more over the term of the plan.
RECOVERY ACTIONS
Relevant stakeholders have been made aware of the existence of this subspecies and its locations. These notifications detail the current status of the species as Declared Rare Flora (DRF) and the associated legal obligations in regards to their protection.
Declared Rare Flora (DRF) markers have been installed at Populations 1, 2, 4, 6 and 12 and Subpopulations 5a and 5b. These serve to alert people working in the vicinity to the presence of the DRF and the need to avoid work that may damage plants or their habitat. Dashboard stickers and posters describing the significance of DRF markers have been produced and distributed.
In July 1998, 150 plants of Verticordia fimbrilepis subsp. fimbrilepis were translocated into a proposed Timber Reserve near Beaufort (Bone and Graham 1998). All plants were grown from cuttings taken from five plants in Population 3 and grown by the Botanic Gardens and Parks Authority (BGPA). The translocation was conducted on an experimental basis and has provided information about effective techniques for future translocations. Three treatments were tested: water, mulch and control (no watering or mulching). The number of surviving plants, height, crown width, reproductive state, number of inflorescences and follicles, and general health are being monitored. By March 1998, 56 of 150 introduced plants (37.3%) were dead. The least number of deaths (26%) were in watered plants and the most (44%) were in mulched plants. In March 2004, only five plants were still alive. Native grass had re-established at the site along with wild oats and veldt grass.
Weed control trials were conducted by DEC Katanning District at Population 1 following an uncontrolled fire in 1990. The population, located on a road reserve, was heavily infested with Veldt grass (Ehrharta longiflora) and the grass-selective herbicide, Fusilade ® , was applied twice per year from 1993 to 1996. Initially, a smaller area of 200m 2 was sprayed covering eight Verticordia plants. Then in 1994, the trial was expanded to include the whole population. During the three years of the trial, no detrimental effects were noted on any Verticordia plants. Although a reduction in grass mass was observed other bulbous and broadleaf weeds, which Fusilade ®
In 1997, Robert Buehrig conducted surveys for new populations of Verticordia fimbrilepis subsp. fimbrilepis. Over 40 waypoints were visited from Aldersyde southward to Woodanilling but no new populations were found (Buehrig 1997).
In 2009, a new population of Verticordia fimbrilepis subsp. fimbrilepis was found south east of Armadale by Fred and Jean Hort.
Some 31,535 Verticordia fimbrilepis subsp. fimbrilepis seeds collected between 1996 and 2004 are stored in DEC’s Threatened Flora Seed Centre at –18 C and 4 C (Table 5). The TFSC test the viability of the seed and the initial germination rate was found to range from 29 to 92%, averaging 53% (A. Cochrane unpublished data).

A further collection of approximately 9.6 g of Verticordia fimbrilepis subsp. fimbrilepis seed from 20 plants at Subpopulation 7b was made in January 2000 by DEC’s Colin Yates. The seed was forwarded to the Botanic Gardens and Parks Authority (BGPA) for storage.
Cutting material from Population 3 was collected in 1994, 1997, 1998, 1999 and 2000 and forwarded to the BGPA at Kings Park for propagation. Of the 3,061 propagules (eight from graftings; 3,053 from cuttings), 702 struck, with an average propagation rate of approximately 25%. The majority of the material grown between 1999 and 2000 was used for a translocation with the remainder since dying. The only living specimens currently at Kings Park are two plants, approximately 12 months old, which were germinated by the TFSC from seed collected at Population 14 on February 2004.
Staff from DEC’s Perth Hills and Great Southern Districts regularly monitor populations. The SRTFCRT and GSDTFRT are overseeing the implementation of this IRP and will include information on progress in their annual report to DEC’s Corporate Executive and funding bodies.
Where recovery actions occur on lands other than those managed by DEC, permission has been or will be sought from appropriate owners/land managers prior to recovery actions being undertaken. The following recovery actions are generally in order of descending priority, influenced by their timing over the life of the plan. However this should not constrain addressing any of the actions if funding is available and other opportunities arise.
The SRTFCRT and GSDTFRT will continue to oversee the implementation of recovery actions for Verticordia fimbrilepis subsp. fimbrilepis and will include information on progress in their annual report to DEC's Corporate Executive and funding bodies.

Weeds are a major threat to most populations and control is required. The following actions will be implemented:
1. Determine which weeds are present and map them. 2.
3.
Control invasive weeds by hand removal and/or spot spraying around the Verticordia fimbrilepis subsp. fimbrilepis plants when weeds first emerge. 4.
Revegetation with site-specific species is required (in Autumn) to maintain low weed levels. 5.
Monitor the success of the treatment on weed death, and the tolerance of Verticordia fimbrilepis subsp. fimbrilepis and associated native plant species to the treatment. 6.
Report on the method and success of the threatment, and effect on Verticordia fimbrilepis subsp. fimbrilepis plants and associated species.

Interim Recovery Plan for Verticordia fimbrilepis subsp. fimbrilepis
Collect seed and other material to preserve genetic diversity
Although a large number of seeds have been collected, the subspecies is not well represented in the seed store. The germination rate for most of the seed collected is relatively low so the actual number of germinants that can be produced is also quite low. Although populations 10, 11 and 16 will be the priority for seed collection as they account for a large percentage of known plants, populations 3, 12 and 15 will also be targeted to ensure as much genetic diversity is captured as possible.

The level of threat posed by rabbits in Populations 4, 7, 8, 13 and 14 appears to vary from year to year. When monitoring ascertains the threat is high, control measures may be required. Control should be undertaken in summer when less green feed is available as an alternative food source.

Feral pigs can damage threatened flora and its habitat when digging in search of food. Pigs can also introduce weed seeds and nutrients and the soil disturbance encourages establishment of weeds. Feral pig activity has been recorded at Population 16 and control may be necessary.

It is recommended that areas of potential habitat, particularly recently burnt areas, be surveyed for the presence of Verticordia fimbrilepis subsp. fimbrilepis during its flowering period between July and December.
All surveyed areas will be recorded and the presence or absence of the subspecies documented to increase survey efficiency and reduce unnecessary duplicate surveys. Where possible volunteers from the local community, Landcare groups, wildflower societies and naturalists clubs will be encouraged to be involved.
Conduct further surveys Responsibility: DEC (Perth Hills and Great Southern Districts) through the SRTFCRT and GSDTFRT Cost: $5,000 in years 1, 3 and 5

Staff from DEC’s Perth Hills and Great Southern Districts will liaise with relevant land managers to ensure that populations of Verticordia fimbrilepis subsp. fimbrilepis are not accidentaly damaged or destroyed. Indigenous consultation will also take place to determine if there are any issues or interests in areas that are habitat for V. fimbrilepis subsp. fimbrilepis.

The importance of biodiversity conservation and the protection of Verticordia fimbrilepis subsp. fimbrilepis will be promoted to the public. This will be achieved through an information campaign using local print and electronic media and by setting up poster displays. An information sheet that includes a description of the plant, its habitat type, threats and management actions, and photos will be produced. Formal links with local naturalist groups and interested individuals will also be encouraged.

If Verticordia fimbrilepis subsp. fimbrilepis is still listed as Threatened at the end of the five-year term of this IRP, the need for further recovery actions, or a review of this IRP, including an evaluation of the plans performance, will be assessed and a revised plan prepared if necessary.
