Having structured the land, and then forming the slopes and pathways of STEF, our next step was to lay the turf on the site. It is now late April, and in order to prepare the site for the heavy rain of the monsoon season in the months ahead, and to avoid soil erosion on the slopes and banks from the water runoff, over 9000 square metres of turf needs to be laid to bind the soil together – assisted by the newly planted trees.
The technique of creating pasture and grassland on previously cultivated ground is somewhat different in Thailand compared to the West. Instead of using grass seed, or long strips of turf, here the turf is cut down small square pieces, and these are then fixed to the soil with a wooden skewer. With grass seed, the heavy rain of the monsoon would saturate the water content of the soil, leading to water runoff and the seeds would simply be washed away and lost altogether. The first batch of turf was planted on the bank east of the first pool, working backwards towards the elephant pool. The work was completed by the wonderful and hardworking couple who have been working on this land for over 40 years, under the supervision of Jake and some of his colleagues.
Whilst the turf gives the soil structure, it is also planted for a number of other reasons. As the welfare of the elephants at STEF must be the first priority, it is important that we structure the site to have widespread areas where the elephants can naturally graze. Natural grazing is a key factor in maintaining a high level of welfare as it gives the elephant choice and diversity of food, as well as allowing the elephant to use the full range of their trunk’s abilities.
It has been tough work planting the turf, but worth the effort as we are really starting to visualise what this superb ecologically sensitive re-creation will look like and where the elephants will roam. Here is Ollie’s 41-second video of the new-laid turf:

The southern region of Thailand, where the Ban Ton Sae STEF site is located, really has only two seasons – the wet and the dry. These seasons do not occur at the same time on the east and west sides of the southern peninsula. On the west coast, where STEF is located, the southwest monsoon brings rain and often heavy storms from April through to October, while on the east coast the most rain falls between September and December. Overall the southern parts of Thailand get by far the most rain, with around 2,400 millimetres every year, compared with the central and northern regions of Thailand, both of which get around 1,400 millimetres.
Because of this, before the next stage of laying the turf, it has been necessary to equip the site with sufficient irrigation and drainage. As the weather is naturally unpredictable, the irrigation was installed as a backup for any prolonged dry spell.
It was vital to select the correct sized water pump and this was then connected to a water supply linked to source of the pools. These pipes were then directed up and along the slope by the pools to where the turf is planted, with specially-designed holes to regulate the release of water along the pipe. With the drainage, we have to ensure the site does not flood as this could lead to erosion of the loose, freshly-moved soil, and damage to the turf by over saturating it. We had 25 sections of large concrete drainage pipes delivered and installed in order to prevent this soil run-off and flooding.
Now we are close to the rainy season, it is crucial that we prepare the site properly to ensure our hard work up up to now is not just washed away…
