Welcome to International Environmental Weed Foundation (IEWF)
and Restoring Natural Capital Alliance (RNC Alliance) Pacific website.
Last updated December 2015. What's new?
Some plants with berries are spread into our bushland and gardens as weeds by birds - learn more from our new Berry Berry Bad Plant brochure
here (399 kb). This brochure can also be found on our Resources page.
We have also uploaded our last financial years report on the
About us page.
Our aim is to educate about the impacts of weeds on our natural environment,
to restore degraded ecosystems, improve native habitat and improve the natural function of urban landscapes.
One of our projects is the Habitat Network, an example of
Restoring Natural Capital in the urban environment.
See our Habitat Network website
where you can find out about conserving and creating habitat for small birds and other native animals.
In May 2011 this project won awards from Sydney Metropolitan Catchment Management Authority - a 1st (shared) Innovation Award
and a Highly Commended for Urban Landcare. In 2012 we opened a community native plant nursery and community food garden in Ryde in order
to further this project. We continue to work with several Councils to enhance habitat corridors.
For quick and easy identification of common garden weeds, potentially invasive plants and
environmental weeds go to
Web Weed Lookup. Also find out more about what weeds are, how they are spread
and how to control them. You will find lots of weed identification photos to help identify common weeds.
If you have quality weed photos
to contribute please email them to email@example.com with details of scientific name
and location where found.
"Noxious and Environmental Weed Control Handbook" (20140 is available from NSW Departement of Primary Industries
Weed removal & habitat - Before you start...look, listen & consider. (432 KB)
This brochure is useful for anyone involved in weed removal (bush regenerators,
bushcare volunteers and all gardeners). It highlights how some weeds are being used as habitat by small
birds and other native animals
and the need to regenerate or restore native replacement habitat
before this weedy habitat is removed.
Invasive vine control
To raise awareness of invasive vines in gardens and bushland
the following brochure has been produced in English and Mandarin with assistance from Ryde and Hunter's Hill Councils,
Tzu Chi Foundation Australia
and Greater Sydney Local Land Services:

"The introduced flora of Australia and its weed status" publication
An introduction by Rod Randall ex Cooperative Research Centre for Australian Weed Management
and currently the Department of Agriculture and Food, Western Australia:
"This publication is the outcome of a Cooperative Research Centre for Australian Weed Management
project, and is aimed at a large range of users from Commonwealth, state and local government officers,
to researchers, horticulturists, nursery owners, farmers, landscapers, consultants, groups of volunteers
looking after remnant bushland to home gardeners. Everyone who uses plants needs to be aware of the
weed potential of those plants and to be able to make informed decisions about which ones to use in their
operations. I hope to see a time, and not that far away, where the use of weedy plant species will
no longer be accepted in public and private plantings in Australia. This publication is offered to
help people to make responsible decisions in the types of plants they use in the future."

Weeds CRC Australia - link to archived website
A wealth of weeds information can be found on the
archived Weeds CRC website. The Weeds CRC was functional from 1995-2008.
Restoring Natural Capital (RNC)
(RNC) involves any activity that invests in the
replenishment (improved quality) of natural capital (native flora & fauna, biodiversity, water, soils, air
and sustainable land use) and as a result improves the flows of ecosystem goods
and services for the benefit of people and the environment.

Restoring Natural Capital.
Habitat Network - an urban RNC project
The Habitat Network project aims to extend habitat and reconnect isolated populations of
small native birds, which are being lost from our urban areas. By recreating native plant connections
we will improve the ability of our native birds, animals and plants to survive.
Follow this link to find out more about the Habitat Network and to visit the
Habitat Network website.
You will find brochures, resources and links related to habitat creation.
Our brochures and documents can be downloaded and used by schools or for community projects.
Find out about the science behind this project and what you can do.

International Environmental Weed Foundation (IEWF) was registered
in July 2003 and is based in Sydney Australia.
We educate and facilitate projects relating to conservation, improved biodiversity, the restoration
of degraded ecosystems and restoring natural capital.
Our Web Weed Lookup and Know Your Garden's Natives projects help people discover
what may be found in their own backyard and surrounding areas.
These provide excellent resources for schools and their
All of our projects are growing through community involvement.
If you want to be involved, use our resources or join the Habitat Network email us
IEWF as of 2015 has a representative on the Greater Sydney Landcare Network committee and Landcare NSW Council.
We encourge all bushcare and landcare groups in the Greater Sydney area to join the Greater Sydney Landcare Network.

Our conservation project, an important habitat link
between Hat Head National Park and Limeburners Creek National Park
is an example of our active dedication to conservation and restoration.
In 2008 we received a three year Private Land Conservation grant from the
Foundation for National Parks & Wildlife. In 2011 we received an additional 3 years funding assistance. Thank you!
These funds contributed to the removal of bitou bush and other weeds and also to improve biodiversity
in both the dunal and adjoining Littoral Rainforest areas on our project site - For Rest.
If you need weed photos you can copy from this site if you ask us first - please email.
We also include links to other sites who are working on similar projects. If you would like your site
included please contact IEWF at firstname.lastname@example.org.
