The willows out of wollemi project started in 2000 and initially was controlling black willows in the Wollemi National Park and mapping seed sources outside the National Park. The inital 3 year program was managed by NPWS staff and the Friends of the Colo with funding of $84,000 from the NSW environmental trust and the primary control inside the park was completed in 2003. In the final year of the grant the groups also mapped other weed sites in the remote areas of the National Park. Friends of the Colo then expanded the project to map and control black willows in the colo catchment (primarily on public and private land along the river and adjoining wetlands betwen Upper Colo and the Hawkesbury River), whilst they continued to monitoring the river inside the National Park with a bi-annual sweep of the catchment for black willows growing into vew. They also stated treating some of the other weeds sites mapped in 2003. A second grant of $38,000 was received from the NSW Environemental Trust to support this second phase. By 2006 most of the primary black willow control was completed in the colo catchment although the volunteers continute to find black willows growing into viw to this day. Friends of the Colo received a thrird grant from the NSW Environemental trust for $28,000 to continue the treatment and monitoring of all weeds in the remote areas of the Wollemi National Park and by 2011 and the completion of theis grant the remote weed sites are now just being monitored for new seedlings germinating and weeds growing into view. During this period the group also treated crack willows in the Wolgan valley to prevent them from spreading down into the Wollmei NP.
Willow Warriors was originally formed from members of Friends of the Colo and they used the skills and equipment acquired in the Willows out of Wollemi program to map and treat black willows in other catchments across South East NSW. WWillow Warriors volunteers contirnue to assist with the Willows out of Wollemi project by participating in monitoring trips inside the Wollemi National Park and also from upper colo to the Hawkesbury river and adjacent wetland.
Here is a summary of the invasive willow taxa treated in the colo catchment over the years.
Here is the final report for the first Environmental Trust Grant.
Here is the final report for the second Environmental Trust Grant.
Here is the final report for the third Environmental Trust Grant.
Areas and lines in Red mean the target weed (primarily Black Willows) exisit and has not been treated.
Areas and lines in Yellow mean the target weed (primarily Black Willows) were treated on the last activeity and monitoring should continue in a 2 year cycle to ensure they died and to look for other black willows growing into view.
Areas and lines in green mean the target weed (primarily Black Willows) were not found onthe last trip and so monitoring can be in a five year cycle.
Areas and lines in purple mean the section of river has not been paddled by us and it is unlikely the target weed (primarily Black Willows) will be found in that section.
Areas and lines in Orange mean the section of river has another type on invasive willow (probably a crack hybrid) and is highly invasive and should be monitored. It also indicated a river where crack willows have been treated on the last trip on a section of river leading into an area of high conservation value and so it should be monitored.

This project was initially a black willow monitoring project to follow up on an earlier control project. But the project expanded to treat crack willows on 15 properties where we had landowner consent to improve river health and protect the habitat of the endangered Booroolong Frog and Tumut Grevillea. As there is no funding or local agency support to remove the large woody debris the project focuses on removing the smaller crack willows and any black willow or crack willow hybrid seedlings we find.In 2010 & 2011 the catchment had two large flood events and then in 2012 a 1 in 100 yesr flood event occurred which remove a lot of the riparian vegetaion including the remaining crack willows and widened the river in several places

Willow Warriors are involved in two linked projects on the Upper Murrumbidgee River.
1) A regional willow mapping project run by the Upper Murrumbidgee Catchment Coordinating Committee (UMCCC) for which Willow Warriors are providing willow mapping data along the sections of river we can paddle. To date we have provided willow data by taxa in 200meter transects along the Murrumbidgee river from Cooma pumping station to McLeods Road, Hall. This data will be consolidated with other data sources from the smaller waterways and wetlands, which is to be used to review the results of Willows Management in the upper catchment.
2) A black willow control project run by the Upper Murrumbidgee Landcare Committee specifically targeting Black willlows. Willow Warriors provided the mapping data and are treating the black willows where we have landowner consent.

The Cecil Hoskins Nature Reserve is located in the Southern Highlands of NSW on the banks of the Wingecarribee River. It is located in the upper third of the Wingecaribbee River sub catchment.
Almost half the area of the reserve is comprised of a lagoon formed by the backed up waters of the Bong Bong Weir. Consequently the reserve is an important habitat for native bird species and in particular wetland birds.The Nature Reserve is managed by the NSW National Parks and Wildlife Service through the Cecil Hoskins Nature Reserve Plan of Management.

Willow Warriors are assisting local stakeholders the Wingecarribee Shire Council, Sydney Catchment Authority, Hawkesbury Nepean CMA National Parks and Wildlife Service and Department of Lands to control invasive willows including Crack Willows and Grey Sallow Willows along the Wingecarribee River. The control of these two types of willows have been split into two projects as the issues, control techniques and future monitoring processes are substantially different.

The Lower Wollondilly invasive willow control project is mapping and, where we have consent, treating invasive willows including Black Willows, Grey Sallow Willows and Crack Willows). To-date the project has focused on the section of the Wollondilly between the Wingecarribee Junction and Goodmans Ford. Crack Willows have been included in the project as there were only a small number of crack willows in this section of river and most were small or medium size and so treating them now would prevent future spread and keep the amount of debris low. There are a few properties that did not give consent and so there are about a dozen willows upstream of Goodmans Ford plus the willows on the property at Goodmans Ford. The landowner at Goodmans Ford is monitoring the willows arround the ford for evidence of Willow Saw fly attack and the impact it is having on the willows. The river between Wollondilly Junction and Goodmans Ford is now in the monitoring phase and will be monitored biannually.
If consent can be obtained this protect will continue the treatment downstream of Goodmans Ford in the future where we also expect to find Black Willows. Willows in this section have been mapped by NPWS.
A willow mapping trip down to the Wingecarribee junction will also be carried out in the future when water levels allow for the river to be paddled.

The Willows out of Our Rivers (WOR) project does not have the goal of removing all willows from Australia. The project has two linked overriding objectives. The first is to map willows by taxa and also look for galleries of seedlings, to determine where the varieties of willows that spread by seed are located, and then work with the community to treat the seedlings and the taxa or trees producing the seed. The reason we have selected whitewater rivers is not just because we enjoy whitewater paddling, but it is because these rivers flow through or adjacent to land managed not for agricultural production but for it's conserrvation values. Our second over riding objective is to assist public and private landowners, who manage their land for it's conservation values, to control willows on their land. The link betwen the two arises because managing the spread of willows vegetatively along a river from agricultural land is not all that difficult it just requires a biannual monitoring program at the upstreaam end of a property where willows have been removed. But monitoring the spread of willows by wind blown seed across or between catchments is very difficlut and requires planning and broad scale managment.
There is more detail on the Project and it's proposed outcomes and objectives below.

The Hawkesbury Landcare Source to Sea paddle was first run in September 2009. The event was funded by the Hawkesbury Nepean Catchment Managements and was run to showcase the work done by landcare and bushcare volunteers, private landowners and public landmangers with funding received from funding bodies like the Hawkesbury Nepean Catchment Management Authority and the NSW Environamntal Trust, Envirofund or the new Caring for Our Country program or Department of Lands or the Sydney Catchment Authority.
A group of paddlers kayaked from the Warragamba river junction on the Nepean to Pittwater over five days stopping of at sites restored by landowners contractors and landcare amd bushcare volunteers.

Conservation Objective:
To protect rivers, creeks & swamps in the Greater Blue Mountains World Heritage Area (GBMWHA) and wetlands in the Hawkesbury floodplains by removing the remaining black willow trees from along the Hawkesbury Nepean River.
Black willows are a Weed of National Significance www.weeds.org.au/WONS/Willows They spread by windblown seed up to 60km & a single large tree can produce tens of thousands of seed that spread along rivers & creeks & into wetlands, Black Willows form monocultures, shading out Casuarinas, Bottle Brush, Tea Trees, Sandpaper figs, Lilly Pilli, Phragmities reeds and other native, seed bearing, plants that are the food source of many native birds.
What we do:
Willow Warriors organise a kayak paddles along the Nepean River to poison Black Willows using bioactive glyphosate which is approved for use along waterways by volunteers . Volunteers & parks staff have already removed Black Willows from the Colo & Grose River sub-catchments that flow through the Greater Blue Mountains World Heritage Area . Hawkesbury River County Council, Willow Warriors, Wetlandcare Australia and Hawkesbury Nepean Catchment Management Authority are partners in a two year program to remove Black willows from the catchment.
