FORESTRY nursery practice provides young seedlings, particularly during the critical period following germination, with conditions in which the necessary protection and adequate soil moisture are ensured. In the field, direct seeding in partially buried bamboo sleeves will ameliorate the seedling environment. However, under field conditions it is not feasible to augment soil moisture by watering, and the plant is therefore dependent on rainfall, which in many cases is unreliable and insufficient. Recent work by Glover and Gwynne1 has demonstrated that the interception of rain by the aerial parts of established plants can concentrate otherwise ineffectual light showers of rain into useful quantities of water within the root range of the plant. An experiment on the direct seeding of three commonly grown exotic species Pintus radiata, P. patula and Cupressus lusitanica at Muguga, Kenya (1° S., 37° E., altitude 6,800 ft.), has shown that a rainfall conductor stick implanted in the soil adjacent to the sown seed increases the seedling survival rate, when used in conjunction with the bamboo sleeve technique (which will be described elsewhere).
