CREATING A NATIVE VEGETATION INSECTARIUM

Putting research into practice with an on-farm trial site

This project is supported by the PPWCMA, through funding from the Australian Government’s National Landcare Programme

The multiple benefits of having native vegetation

• n your farm
• Shelterbelt
• Habitat and food source for insects- (insectariums, beetle

banks, insect corridors)

• Biodiversity values (consider offsets in planning applications)
• Meet obligations in Environmental Assurance programs
• Bush Food production- income diversification

• 1. Biodiversity Interactive Map: Look up the relevant Ecological Vegetation Class (EVC)

for your property Weblink: http://mapshare2.dse.vic.gov.au/MapShare2EXT/imf.jsp?site=bim

Step 2: Zoom in to the area you are looking at. I select a scale of 1:10,000 or 1:20,000 depending on how much information is needed. Step 3: Click on the yellow folder and turn on the 2005 EVC layer. Then refresh the map.

Click on legend to bring up the map key for each EVC

Click on the pdf icon and fill out the

• details. Click OK. A hyperlink with

• benchmark. Below is the Highlands-

Southern Fall as Yellingbo is in this bioregion. Open the word or pdf file. Look up the relevant EVC numbers listed in your property EVC Map.

Look for plants which you have seen featured in the research as appropriate insectarium species Quite a few relevant EVC’s have bush foods, you just need to know what you are looking for Plant a mix of EVC plants depending on the layout

• f your insectarium

The more plant diversity and layers, the better the habitat for diverse beneficial insects

CUSTOMISED SITE PLANTING GUIDE Using the EVC list you have for the property, start to highlight plants you know are highly beneficial in an insectarium: Sweet bursaria, wallaby grass, prickly tea-tree are the three HERO plants What else is on your list that matches your planting space/layout and will provide nectar and pollen? Shelterbelt- Upper and Middle story flowering plants Insectary plants- HERO plants and similar ones found in your EVC. Make sure there is diversity in your strata layers and include groundcovers. The customised list for Fieldberberry Farm is available at: http://www.ppwcma.vic.gov.au/news/publications/ NB: this is specific to this farm and is a GUIDE only.

• Upper story (shelterbelt)- E. olida
• Middle story- (shelterbelt)- Bursaria spinosa, Prostanthera lasianthos
• Lower story- grevillea, Acacia, correa sp, round leaf mint bush, parrot pea, bush

pea, heath, daisy, honeypots, river mint, lilies, grasses

• Groundcovers- native violet, running postman, pussytails, muntries etc

Your insectarium layout can be any design you like

• Grasses under vine or inter-row, end of row strainer posts
• Surrounding a dam
• Land class zoned unsuitable for production
• Garden beds
• Headlands, buffers and re-vegetated shelterbelts

It’s about insect corridors and connectivity to native vegetation

Is it working?

• Spring in Victoria hasn’t been kind if you want to monitor insects!

10 sticky traps, one week (7 days) each month Sept-Jan 3 pit fall traps in the main insectary planting, one week each month Sept-Jan Monitoring for increases in abundance and diversity of beneficial insects over next 2 years, longer if my RLF project is re-funded!

Is it working?

• Spring in Victoria hasn’t been kind if you want to monitor insects!
• However, 7 weeks after planting, some native plants were already flowering

and spiders moving in to the insectary
