Revegetation Report March 2025
Carbon Positive have published their formal assessment of the first two years plantings. Here is a summary:
2023 Plantings in Southern Paddock
Minimal variability between the average density of plots (min 520 live trees/ha, max 960 live trees/ha).
Overall, tree health is excellent (4.68/5), and minimal pest damage was observed (0.44/5).
Eucalyptus was the most prevalent genus, densely planted in several rows, particularly in the southeast corner. Although this does not seem to have adversely impacted health or growth.
Average density increased by 14% since the last monitoring assessment (613 live trees/ha in 2024 to 700 live trees/ha in 2025), indicating an increase in seed germination.
Average height increased by 124% since the last monitoring assessment, rising from 0.24m in 2024 to 0.49m in 2025.
The tallest tree measured was a 1.1m Eucalyptus.
Natural regeneration of Acacia species between planting rows.
2023 Plantings in Northern Paddock
Average density ranged from 1,100 to 2,360 live trees/ha for plots 4-11, while plot 12 was an outlier, with 80 live trees/ha.
Overall, tree health is good (4.31/5), and very minimal pest damage was observed (0.09/5).
Excellent species diversity with an average of 11 unique species per plot (min 8 and max 16).
Lower seedling health and seed emergence in areas with densely established natural regeneration were noted.
Excellent seed germination across plots.
Average density increased by 6% since the last monitoring assessment, rising from 1,372 in 2024 to 1,453 in 2025. This suggests that the 2024 infill planting was successful. Additionally, seed germination may have contributed to the increase.
Average height increased by 123% since the last monitoring assessment, rising from 0.23m in 2024 to 0.5m in 2025.
The tallest trees measured were a 1.5m Acacia lasiocalyx and a 1.5m Calothamnus quadrifidis.
Acacia assimilis was the most prevalent species.
2024 Plantings in Northern Paddock
The average density was highly variable between plots (between 680 and 4,420 live trees/ha).
Overall, tree health is excellent (4.48/5), and very minimal pest damage was observed (0.03/5).
Some rows were missed by direct seeding, towards the south-west of the planting area. Plots 14, 16, and 18 have no evidence of being direct-seeded.
Excellent species diversity with an average of 11 unique species per plot (min 8 and max 17).
Lower seedling growth and seed emergence in areas with densely established natural regeneration were noted.
The tallest trees measured were a 1m Acacia coolgardiensis and a 1m Acacia assimilis.
Acacia assimilis was the most prevalent species.
Notes:
1. Live trees only 2. Health rated from 0 to 5, where 0 equals dead (i.e. no green leaves), 1 equals 0-5% health, 2 equals 5-25% health, 3 equals 25-50% health, 4 equals 50-75% health, and 5 equals 75-100% health 3. Pest damage rated from 0 to 5, where 0 equals no damage, 1 equals 0-5% pest damage, 2 equals 5-25% pest damage, 3 equals 25-50% pest damage, 4 equals 50-75% pest damage, and 5 equals 75-100% pest damage
