Plant Health Questionnaire – Instruction Guide

How to undertake this questionnaire

Your ranger group has 1 x ranger 6hrs, 1 x vehicle 3hrs to complete this questionnaire. The way in which you can use that time is quite flexible. We would like to offer some suggestions on how to complete the questionnaire, that you can fit to your individual conditions. The survey has four sections:

  • Top Watch Gardens
  • Wild rice
  • Aquatic weeds
  • Terrestrial weeds

Top Watch Gardens

Please drive to garden sites located in your community or school, note their location(s) and gather the following information:

What is the garden’s name?

What size is the garden?

width and length in metres

Is the garden maintained/cared for?

Yes, no, seasonally or has been in the past etc

Approximately how many people use this garden?

Contact details for the main contact for the garden(s) (with their permission)?

name, phone number

What food plants are growing in the garden?

(for example, banana, citrus, beans, pumpkins, mango, or tomatoes)

Please take some pictures of the garden

The entire garden, some trees and garden beds

Is bush tucker grown in this garden?

You may need to discuss permissions for visiting and collecting information and/or talk to schools/community groups beforehand.

This activity should take approximately two hours ranger time and one-hour vehicle time (depending of course on how far it is away from your ranger base etc.)

Wild Rice

This activity is a desktop activity only and only needs to be completed if you have knowledge of wild rice populations in your management area.

If you do have this knowledge or know someone who does, we would appreciate information on where the local wild rice populations are and how easy they are to access, so that wild rice could be monitored for pests and disease, by yourselves or scientific staff.

This exercise should take one hour or less of ranger time.

Weed rapid survey (Aquatic and Terrestrial) for new or unusual weeds

This weed survey activity should use the time you have remaining for this activity (approx. three hours ranger time and two hours vehicle time). Please take pictures and note the location of any new (first noticed in the last 2 years) or unusual weeds, terrestrial and or aquatic (if you have them) and add that information to the questionnaire map/s.

If you don’t have access to rivers, lagoons, and wetlands as a part of your management area please refer to the next task on terrestrial weeds.

Aquatic weeds

If you have access to rivers, lagoons, and wetlands as a part of your management area we would like you to undertake a look around your local community to look for new or unusual aquatic as well as terrestrial weeds.

How to look for new or unusual aquatic weeds:

What: Water weeds can be vines, shrubs or trees, grasses, and a diverse array of non- woody plants including algae.

Where they grow: In the water, floating free on the water surface, rooted in the mud and emergent above the water’s surface; growing around the margins of bodies of water.

Where you should look: Rivers, permanent and seasonal creeks, billabongs, swimming holes, ponds, dams, irrigation canals, soaks, springs, swamps, roadside or other drains that fill with water for extended periods.

Information to note at any locations of new or unusual aquatic weeds:

Name of aquatic weed if known?


Is this the first observation of this weed?


(Yes / No)

How big is the weed infestation?

(width and length in metres)

Name of water way / water body?



Is the aquatic weed in deep water?


(Yes / No)

Would you need a boat to access the weeds?

(Yes / No)

Can you access them during the wet season?



Are there any safety issues with site access

(if yes, please describe i.e. crocodiles, fast running water etc.)?



Don’t forget to take pictures of any new or unusual aquatic weeds to upload as a part of this survey

Terrestrial weeds

Please find below suggestions of where to look for potential new terrestrial weeds:

  • Landfills/waste transfer stations
  • Barge landings
  • Airstrip/airport environments
  • Local shops
  • Campgrounds, especially moist sites near ablution blocks
  • Ditches and drains
  • Edges of dams and weirs and sites where seasonal flooding occurs in the wet season.
  • Main road/community road gravel and road base storage areas
  • Sites where bulk bags containing landscaping materials are stored
  • Sites where building materials are temporarily stored
  • Sites where earth-moving machinery is stored
  • Other transport storage areas
  • New subdivisions
  • Livestock enclosures
  • Around of community gardens

* Only look in places where access is given, and the environment is safe.

Information to note at any locations of new or unusual terrestrial weeds:

What is the weed name (if known)?


Is this the first observation of this weed?


(Yes / No)

How big is the weed infestation?


[width and length in metres]

Don’t forget to take pictures of any new or unusual weeds to upload as a part of this survey
