2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
The local species of juniper trees (Juniperus seravschanica, Juniperus turkestanica and Juniperus semiglobosa) are rarely rejuvenating under conditions of intensive grazing and are difficult to propagate in nurseries. The technology describes the propagation of these important trees from locally collected seeds and their cultivation.
2.2 Detailed description of the Technology
Description:
The technology is used to produce seedlings of juniper trees in the forestry nursery for further replanting in the natural juniper woodlands of the local forestry enterprise. Juniper woodlands are important ecosystems of the mountains of Central Asia, which are typically used for livestock grazing. The tree cover fulfills important functions for the maintenance of ecosystem services – local microclimate, regulation of water infiltration and surface runoff, biodiversity, esthetic value and recreation, fuelwood etc. The local juniper species rarely rejuvenate naturally. Factors hampering natural rejuvenation include intensive grazing, competition by other plant species and weather conditions. Loss of old juniper trees due to natural losses, damage and cutting combined with lacking rejuvenation causes the degradation and loss of juniper stands. Forestry enterprises in Central Asia often in such situations instead of the difficult to cultivate and slowly growing native juniper often plant non-native arborvitae Thuja spec. These non-native species do not provide the natural ecosystem functions of native juniper and are less adapted to the local site conditions.
The purpose of the described technology is therefore the provision of planting material for the rehabilitation of degraded juniper woodland pastures with native trees.
Forestry workers collect ripe juniper fruits from their natural stands during late fall (November – December). The fruits are than mixed with sand and stored in a cold place until spring, or they are further processed to accelerate germination.
In the first case in spring the fruits are crushed on a clean concrete surface either by trampling with boots or by using a vehicle. Afterwards the crushed fruits are washed and air-dried. With the help of wind and a sieve the dried seeds are cleaned from other parts of the fruits. The seeds are then stored under a 5 cm layer of sand until fall and sown in fall (October-November)
In the second case the fruits are initially for one month stored in a barrel with water. Then the fruits are crushed and cleaned as described above. The cleaned seeding material will be stored in a pit, covered with moist sand mixed with some dung from horses or cattle. After one month the seeds are sown into the nursery.
In the area of the forestry enterprise brown bears feed on juniper fruits. In the bear feces many juniper seeds can be found, sometimes directly germinating. This “natural stratification” is sometimes used by forestry workers if they find substantial amounts of bear feces consisting of juniper fruits.
The seeds are sown directly into the soil in the nursery. Each, germination rate and survival are 90%. After five years the seedlings have grown to a height of about 20-30 cm, their roots reach 20 cm deep into the soil and they are ready for replanting.
The seedlings are carefully dug out, deep enough not to damage the root system and together with the earth covering the roots. They are wrapped in plastic bags for keeping the earth cover of the roots during transportation. During the planting the seedlings are put into the tree pits together with the soil from the nursery still covering the root system. The planted seedlings are watered.
After planting the seedlings are five years cared for, including weeding and if necessary watering either from a canal, if available, or with barrels.
The use of containers for seeding and replanting has not yet been tried. It may protect the root system during replanting and reduce the amount of soil to be used for this purpose. On the other hand the technology without containers is not dependent on their availability, no garbage in form of plastic containers is left in the tree pits and the larger amount of soil from the nursery may ease establishment of the seedlings at the woodland rehabilitation site.

6.3 Exposure and sensitivity of the Technology to gradual climate change and climate-related extremes/ disasters (as perceived by land users)
Gradual climate change
Gradual climate change
Season | increase or decrease | How does the Technology cope with it? | |
---|---|---|---|
annual temperature | increase | moderately | |
seasonal temperature | dry season | increase | moderately |
annual rainfall | decrease | moderately | |
seasonal rainfall | wet/ rainy season | decrease | moderately |
seasonal rainfall | dry season | decrease | moderately |
Comments:
Juniper trees grow at sites with a broad range of climate conditions, some of them rather extreme. They can therefore expected to cope with increasing aridity and short-term extremes at their natural stands. In the nursery drought can be compensated by watering, although intensive watering may hamper adaptability and survival of replanted saplings.
6.4 Cost-benefit analysis
How do the benefits compare with the establishment costs (from land users’ perspective)?
Short-term returns:
neutral/ balanced
Long-term returns:
slightly positive
How do the benefits compare with the maintenance/ recurrent costs (from land users' perspective)?
Short-term returns:
slightly positive
Long-term returns:
positive
Comments:
Rehabilitation of juniper woodlands provides only long-term economic benefits. Costs of cultivation in nurseries are partly compensated by combined growing of decorative coniferous treees (thuja, spruce) for commercial sale.
6.5 Adoption of the Technology
- single cases/ experimental
6.6 Adaptation
Has the Technology been modified recently to adapt to changing conditions?
No
6.7 Strengths/ advantages/ opportunities of the Technology
Strengths/ advantages/ opportunities in the land user’s view |
---|
The technology is well established for the propagation of native juniper saplings and for the rehabilitation of juniper woodlands. |
The technology has the advantage of allowing for the establishment/rehabilitation of tree stands with native species, which are adapted to local site conditions and are an integral component of the ecosystem. |
The area of juniper woodlands in various stages of degradation in the country makes up many ten thousands of hectares. While resources (labour, nursery capacity) are prohibitive for replanting juniper in all areas, the technology allows for rehabilitation of key areas, identified by need and/or rehabilitation potential. In particular other forestry enterprises in the country with juniper woodlands could potentially adopt the technology. |

---|---|
Same as land user's view. | Consider facilitation of natural rejuvenation through grazing management (temporary exclusion of sites or reduction of grazing intensity or adaptation of herd compostion - no goats). |
Same as land user's view. | Natutral feature of the native juniper tree species, which cannot be changed, but needs to be taken into consideration during production of planting material and in the management of the woodlands. |
Over grazing may hamper success of woodland recovery. | Support establishment of replanted saplings through grazing management (temporary exclusion of sites or reduction of grazing intensity or adaptation of herd compostion - no goats). |

7.4 General comments
The documentation of the technology is based on the site visit at the nursery and one single interview with the forest protection engineer of Shahriston Forestry Enterprise. It was not possible to observe the entire process of propagation, cultivation and replanting of juniper and to verify the recieved information. The compiler took into consideration additionally his ecological knowledge and expertise. Given the importance of juniper woodlands as ecosystems in Central Asia, their large-scale degradation, the difficulties of their rehabilitation and the prevalence of non-native species in reforestation projects this technology deserves documentation and further consideration.
