Making revegetation ‘climate ready’
As a Landcare group, one of our main interests is to increase ecological resilience in our local area. Many of our landscapes have been cleared of vegetation in previous decades, so we have the task of supporting landholders to plant trees and shrubs to replace those that are missing. The benefits of revegetation are manifold. They include providing habitat for a range of native animals; controlling erosion and salinity; increasing farm productivity through nutrient cycling and shade and shelter for stock; and drawing down carbon from the atmosphere.
But as weather patterns become more variable and we experience more climatic extremes, we need to think about which plant species – and which plant genetics – are most appropriate in our revegetation efforts. We are forced to ask will our local plantings be able to survive our future climate?
Up until recently, it has been common for people to preference locally sourced seed when re-planting. This has been based on the idea that such plants will be best adapted to local conditions. However, there is growing understanding among scientists and land managers that we need to shift our focus to plants that can persist as the climate changes. This involves looking at which plant species are most appropriate by focussing on species that have a wide distribution and grow in our area and also in hotter areas, and increasing the genetic diversity of our tubestock so they have the best potential to adapt over successive generations.
Our Landcare group has been tackling this issue for the past several years, working with scientists and AdaptNSW to find the best way forward. There are several key steps involved:
- understanding our local future climate,
- analysing whether selected local species can survive in climates like the one projected for our area, and
- sourcing seed for those likely-to-survive species from a range of areas to increase the genetic diversity of our plantings.
Planting the right species with good genetic diversity gives revegetation projects the best chance of survival into the future. It’s not just about making sure the individual tubestock will grow, but that future generations of those plants will be able to survive and thrive.
Luckily there are some good resources available for farmers, land managers and groups interested in climate ready revegetation. The Royal Botanic Garden Sydney has launched the Restore and Renew Webtool (https://www.restore-and-renew.org.au/), which is a wonderful way for people to incorporate both climate change and genetic information when sourcing seed or plants. The NSW Niche Finder is invaluable for those who want to dig further into climate variables and species distribution (http://www.nswnichefinder.net/). For future climate information, the CSIRO and Bureau of Meteorology have joined forces to provide a user-friendly online tool (https://myclimateview.com.au/). And AdaptNSW also provides projected climate change information for different regions of the state (https://www.climatechange.environment.nsw.gov.au/projections-map).
The Yass Area Network of Landcare Groups also has detailed information about our work on climate ready revegetation and relevant resources our website: https://yan.org.au/projects/climate-ready-revegetation-project
As the climate changes, our revegetation efforts are more important than ever. And we need to make sure that they are ‘climate ready’ so that their benefits persist well into the future.

Trace minerals are required for optimal growth, reproduction, and immunity. Optimising trace mineral status relying solely on oral supplements across a herd may fail because of variation in individual intake and reduced absorption due to antagonism of other ration components and minerals. The use of injectable trace mineral supplements has been associated with positive reproductive outcomes including improved conception rate, increased odds of pregnancy and greater final in calf rate. A study conducted on 2,168 dairy cows, administered injectable trace minerals, four weeks prior to calving and again four weeks prior to the start of mating showed treated animals had a 3.3 per cent greater final in-calf rate, and a reduced time from start of mating to conception, compared to control animals 1 . The Importance of B12 Dr Carl Eden, Technical Services Veterinarian with Boehringer Ingelheim says “Vitamin B12 is sometimes referred to as a ‘super vitamin’ because it is only required in very small amounts but vital to many essential metabolic pathways. However, demand for B12 can vary considerably during the year and we see serum levels of B12 fall at critical times, such as the first few months after calving.” Vitamin B12 contains cobalt, so deficiency in cobalt can lead to deficiency in vitamin B12 because ruminants get most of their B12 as a byproduct of ruminal fermentation where the bacteria in their rumen assemble B12 from cobalt for use by the cow. Sub-optimal trace mineral and vitamin B12 status at calving, mating, and drying off has been shown to negatively impact growth, reproduction, and immunity. Using a trace mineral injectable containing vitamin B12 can improve trace mineral and vitamin B12 status at these critical times. Marks-Min with Vitamin B12 – The Evidence In the largest trace element study to date, Marks-Min Injectable Trace Mineral with Vitamin B12 demonstrated remarkable results when compared to a reference trace mineral injection. “Given the differences between Marks-Min and other products on the market, we wanted to generate a compelling data set to demonstrate how effective it was compared to the pioneer product. We entrusted this work to a third-party research company” says Dr Eden. “We chose farms that were at the top of their game from a reproductive perspective. We made sure that the farms had no evidence of trace element or vitamin B12 deficiencies or excess.” Across all outcomes of interest, Marks-Min demonstrated clear non-inferiority when compared to the reference product. Outcomes measured included submission, pregnancy and conception rates, and six week in-calf rate. Marks-Min demonstrated it is highly suited as an alternative treatment to the reference product.
