What this project is
Reforestation is only successful if seedlings survive. A planting program can plant thousands of seedlings and still fail if the wrong species went to the wrong site, if planting quality was poor, or if drought, browsing or weeds killed them afterwards. A tracking system follows seedlings from nursery batches through transport and planting to survival checks, so managers know what was planted where, of which species and batch, and how much of it is still alive months later.
Batch identity matters. Seedlings from different nurseries, seed sources or batches perform differently. If planting records do not link seedlings to their batch and seed source, a survival problem cannot be traced to its cause: was it the site, the species, the batch, or the planting? The system should keep that link, so a poor survival result in one area can be compared with the same batch planted elsewhere.
Core features
- Nursery batch records with species, seed source, quantity and dispatch dates
- Planting records by site, block and species, linked to batches
- Planting quality checks: spacing, depth and handling recorded at planting
- Survival surveys at set intervals after planting, with survival rates by site, species and batch
- Replanting planning for areas where survival falls below the target
- Reporting by site, species, batch and season, showing what worked and what did not
How it is built
- Define the planting sites and blocks first, with species assignments for each
- Build nursery batch and planting records, then survival survey tools
- Add replanting planning for failed areas, then reporting by species and batch
- Test survival surveys in the field, with offline capture where sites are remote
- Pilot on one planting season, following batches from nursery to first survival survey
Technology considerations
Field capture in remote planting sites needs offline tools. Planting crews and survey teams work where connectivity is poor, so records must be captured offline and synced reliably. Location accuracy matters: a survival survey that cannot be linked to the right planting block is useless, so block boundaries and planting locations should be recorded from maps, not from memory. Survival survey design needs thought too: sample plots that represent the block, surveyed at consistent intervals, give comparable rates; ad hoc counts do not.
Species and site matching is where the data pays off. Survival rates by species and site type, over several seasons, show which species suit which sites and which do not. That evidence should feed future species selection, but the system should present it as evidence, not as an automatic prescription: local knowledge and site conditions still matter, and a species that failed in a drought year may succeed in a normal year.
For the first version, follow one planting season's batches from nursery dispatch to first survival survey, with planting blocks, species and batch links intact. Reforestation managers judge the system on whether a survival failure can be traced to site, species or batch. A system that does that for one season, with replanting planned for failed areas, is the evidence base for improving the next season's planting.
Challenges to plan for
- Seedlings from different batches mixed at planting, losing batch identity
- Survival surveys that are skipped, leaving failure undiscovered until it is too late to replant
- Planting quality problems, such as poor depth or handling, that only show up as mortality months later
- Replanting that repeats the same species on a site where it already failed
Who it is for, and its limits
This suits a forestry company, a reforestation program or a public agency planting at scale. It fits programs where survival matters and where planting spans several sites and seasons. It does not fit a small one-off planting, and it is not a nursery management system: it tracks seedlings from nursery dispatch onwards, it does not run the nursery.
A tracking system does not make seedlings survive. Survival depends on species choice, site preparation, planting quality and weather. Tracking shows what survived and why, so the next planting is better. Costs vary with planting area and survey frequency, so confirm with a quote after the planting program is scoped.
Frequently asked questions
What is a batch?
A group of seedlings of one species from one seed source, grown together in a nursery. Batch identity links planted seedlings to their origin, so performance can be compared across batches.
How is survival measured?
By surveying sample plots in a planted block at set intervals after planting, counting live seedlings against the number planted. The result is a survival rate for that block, species and batch.
When should replanting happen?
When survival in an area falls below the target for that site and species. The system flags those areas and plans replanting, rather than leaving gaps to fill with weeds.
Does planting quality matter that much?
Yes. Depth, handling, spacing and timing all affect survival. Recording quality checks at planting lets managers link mortality to planting practice, not just to weather or species.
Can the system compare species?
Yes, by survival rate across sites and seasons. That evidence supports species selection, but it should be weighed with local knowledge and site conditions, not followed blindly.
