Leaf chlorophyll content provides valuable information about physiological status of plants. However, fewer studies have investigated the difference in chlorophyll concentration in leaves of tropical afforestation tree species. Therefore, this study examines the difference in foliar chlorophyll contents of six tropical afforestation tree species namely: Tectona grandis, Pentaclethra macrophylla, Piptademiastrum africanum, Azadirachta indica, Brachystegia eurycoma and Gmelina arborea found in the relict forest in Umudike, South east, Nigeria. A single factor experiment in a completely randomised design in three replicates was employed to analyse the rate of leaf chlorophyll contents. Fisher's least significant different was used to test for significance in mean difference in foliar chlorophyll contents between tree species at 95% confidence interval using analysis of variance. The results of this study showed a significant difference in foliar chlorophyll concentration between the tree species with Tectona grandis having a higher chlorophyll concentration than other trees this could be as a result of its higher vegetative activity which increases its primary productivity followed by Pentaclethra macrophylla while Azadirachta indica having least the chlorophyll concentration. The study further revealed that other indigenous tree species like Piptademiastrum africanum and Brachystegia eurycoma have higher chlorophyll concentration. Further studies should be carry out to examine factors that have contributed informed the differences in the chlorophyll concentration of these trees species, thus this would broaden the understanding of their physiological status and equally encourage there conservation.

This study was designed to evaluate the influence of conservation education advocacy on the youths with regards to career attractiveness. The study adopted a two-stage sampling technique in selecting one hundred and fifty seven (157) respondents from three secondary schools within the operational base of the PANDRILLUS FOUNDATION. The results indicated that majority (49.7%) of the respondents were in Senior Secondary Two (SS2), 59.2% of the respondents were male while 52.2% were within the age bracket of 17-19years. Conservation Education (CE) messages with high index scores above 0.700, profiled by the respondents included impact of deforestation, agroforestry, afforestation/ enrichment planting, land rotation, and global warming/ climate change. Over 75% of the respondents professed that the conservation education has positive impact on them, 99.4% of the sampled respondent showed attitudinal deposition towards career in environmental conservation related discipline. Environmental management, Forestry, Horticulture and landscaping, Veterinary medicine, and Wildlife conservation/management, had well above 50% embrace by the respondents. Development of environmental extension programme, use of methods that motivate listenership and programme evaluation were among the recommendations advanced to enhance the efficiency of governmental and nongovernmental institutions involve in environmental management.
