Nursery
• temporary storage
of seedlings
• provide mangrove
seedlings of the
required species
in the required
numbers and
sizes at a given
time

• Nursery-reared plants
sturdier
• Small seeds not suitable for
direct planting
• Survival along the seafront
is higher for nursery-raised
seedlings (vs propagules)

Mangrove nursery establishment and operation
Steps in mangrove nursery establishment & operation
• Site selection
• Preparation for field collection
• Collection and bagging of wildings
• Collection and planting of seeds/propagules
• Maintenance
• Seedling selection and transport
![Page 7: The ZSL-CMRP Experienceelti.fesprojects.net/2013 Mangroves1/Asis-Loma.pdfEuphorbiaceae 12. Excoecaria agallocha Lythraceae 13. Pemphis acidula Meliaceae 14. Xylocarpus granatum](https://reader030.vdocuments.us/reader030/viewer/2022040718/5e25de7faffd2e17f25960ce/html5/thumbnails/7.jpg)
Mangrove nursery establishment and operation
Site selection
1. Natural tidal flow/ inundation
during spring tide
2. Protection from waves
3. relatively flat, with firm
substrate and well-drained
4. under the shade of
mangrove/other trees
5. proximity to the planting site
6. preferably close to
freshwater supply
7. preferably close to
seed/propagule sources
![Page 8: The ZSL-CMRP Experienceelti.fesprojects.net/2013 Mangroves1/Asis-Loma.pdfEuphorbiaceae 12. Excoecaria agallocha Lythraceae 13. Pemphis acidula Meliaceae 14. Xylocarpus granatum](https://reader030.vdocuments.us/reader030/viewer/2022040718/5e25de7faffd2e17f25960ce/html5/thumbnails/8.jpg)

Mangrove nursery establishment and operation
Preparation for field collection
1. Consult commercial calendars
(with tide levels) to select
suitable date and time
2. Collectors prepare,
appropriate clothes, rubber
shoes/ booties
3. Prepare logistics and materials
Prior to the fieldwork
Bagging can be conducted
from 5-10 Jan and 19-24 Jan.

Mangrove nursery establishment and operation
Preparation for field collection
1. Briefing/orientation
2. Ratio of 1 supervisor
15-20 participants
On the day of the fieldwork
seed/wilding collectors baggers haulers
![Page 11: The ZSL-CMRP Experienceelti.fesprojects.net/2013 Mangroves1/Asis-Loma.pdfEuphorbiaceae 12. Excoecaria agallocha Lythraceae 13. Pemphis acidula Meliaceae 14. Xylocarpus granatum](https://reader030.vdocuments.us/reader030/viewer/2022040718/5e25de7faffd2e17f25960ce/html5/thumbnails/11.jpg)
Mangrove nursery establishment and operation
Collection and bagging of wildings
1. Look for “seedling
banks”
2. Collect wildings not more
than 40 cm (with at least
6 leaves)
3. Use a shovel or digging
blade
soil still attached to
the roots
4. Smaller wildings (10-20
cm long) need to be
conditioned 3-4 mo up
to 1 year in the nursery
Bigger wildings may be
transplanted directly

Mangrove nursery establishment and operation
3. Propagules should not be transported
between islands.
4. Seeds and propagules can be stored
in a shady, cool and dry place and
should be planted within 1 week to 1
month
• 10-20 days for A. marina and A.
corniculatum
• 1 month for Rhizophora spp.
5. Sow and germinate seeds. Water,
fertilize, protect from pest.
• large seeds and propagules
- individual containers
• small seeds
- seedbed prior to transfer in
individual bags

Mangrove nursery establishment and operation
1. Visit nursery at least 2-3 times
weekly
2. Healthy plants have green leaves
and are pest-free
3. Remove diseased plants and bury
them
Maintenance
Pest: Coccotrypes fallax
Remedy: sun-dried or air-
dried for 1-2 weeks prior
to planting in polybags
![Page 21: The ZSL-CMRP Experienceelti.fesprojects.net/2013 Mangroves1/Asis-Loma.pdfEuphorbiaceae 12. Excoecaria agallocha Lythraceae 13. Pemphis acidula Meliaceae 14. Xylocarpus granatum](https://reader030.vdocuments.us/reader030/viewer/2022040718/5e25de7faffd2e17f25960ce/html5/thumbnails/21.jpg)
Mangrove nursery establishment and operation
4. Polybags should be
separated from the
bottom of the nursery
with plastic sheet lining
5. If seedlings are stunted
due to small bags,
transfer to bigger bags
without damaging the
roots.
Maintenance

Mangrove nursery establishment and operation
1. Regularly segregate seedlings by
species and sizes for easy transport
and hauling
2. Prepare crates or modified seedling
carriers
Seedling selection and transport

Mangrove nursery establishment and operation
Onsite/backyard nurseries are easy to set up
and maintain because of access
Use of wildings: using nature’s excess to
save time
