⛰️So happy to make it without walking and 10min faster than last year: 2:34:16 in this amazing half marathon 21.1km with 1271 metres elevation
∆ Average pace 7:23 min/km, starting with 5:50 min/km first 5km.

New Zealand's bold plan to save endangered animals: kill millions of invasive animals Many of New Zealand's unique birds are heading toward extinction. So the country is taking on an ambitious conservation project: eradicating the invasive species that prey on them.

New Zealand aims for Predator Free 2050 - eradication of #InvasiveAlienSpecies which harm native species (especially birds like the kiwi). It will be one of the biggest #conservation programs worldwide 🌍

Cm-scale FVC maps🌱from our best CNN models predictions on 3072×3072 px UAS multispectral tiles for each site (site-specific models).

Model generalisation & transferability 🛰️ We tested 2 setups (A & B) to see when site-specific models beat generic ones. Expanded discussion on limitations + showed how data augmentation can boost robustness as a proof-of-concept.

U-Net models were trained & validated with spatial block CV, including both site-specific and generic models across all sites, to produce more realistic and transferable evaluations. Random CV inflated performance estimates by up to 28%.

🌱📍We tested our CNN approach at 3 AusPlots sites in Calperum Station, South Australia, each representing a different National Vegetation Information System (NVIS) vegetation type: A (low), C (medium), E (dense). Together they cover 29 ha of semi-arid landscape.
