“…The differences in the measured tree size for the 20 sampled tree stands may be attributed to varying degrees of anthropogenic disturbances and tree age. This is consistent with the findings of Iwara et al [33], Martinez-Meza & Whitford [34], Iwara [23] and Ogundele [30] when they attributed high tree size to reduced anthropogenic disturbance. Also, Lalfakawma et al [35], Iwara et al [33] and Ogundele [30] attributed high DBH to the presence of high climax tree species.…”

Also, Lalfakawma et al [35], Iwara et al [33] and Ogundele [30] attributed high DBH to the presence of high climax tree species. However, the high tree sizes measured among the sampled trees in LASU have the tendency for carbon storage.…”

“…In addition, Table 1 and Figure 1 showed that tree size ranged from 0.9 to 3.9 m with a mean value of 2.48 m. Tree size provides a measure of tree performance, and plays a fundamental role in carbon storage or carbon sequestration. This is because large trees are recognized in the literature to absorb more carbon from the atmosphere than smaller trees [30,31,32]. The differences in the measured tree size for the 20 sampled tree stands may be attributed to varying degrees of anthropogenic disturbances and tree age.…”

A sustainable university has been defined as a higher educational institution that addresses, involves and promotes the minimization of negative environmental, economic, societal, and health effects generated in the use of their resources in order to fulfil its functions of teaching, research, outreach and partnership, and stewardship in ways to help society make the transition to sustainable lifestyles. Earlier studies on green innovations have basically centered on the environmental benefits and were purely descriptive in nature. Several others examined the effect of green innovation on soil organic carbon by comparing street trees of species. The present study would contribute to literature using a mixed research approach to empirically investigate the contributions of green innovation on carbon storage and perceived environmental quality in Lagos State University, Nigeria. Data for the study were obtained by collecting 100 surface (0 – 15cm) soil samples with the aid of a soil auger under campus trees, grasses, ornamental trees and vegetables (Amaranthus and green vegetable farms) across different land uses on campus. Also, data on green characteristics (tree height, tree size, canopy cover, density of herbs, basal cover and herbaceous cover) were measured using different ecological procedures, while 655 questionnaire copies were administered to staff and students to ascertain their perceived environmental quality of green innovation. Data obtained were analyzed using averages, simple percentages, One-Way Analysis of Variance, multiple regression analysis and principal components analysis. The results obtained showed that carbon storage significantly varied among the green innovation components with canopy cover contributing over 55% of carbon storage. The study revealed that canopy cover and tree size substantially contributed in carbon storage with canopy cover being more effective. PCA result identified beautification of LASU (19.8%), flood control (18.8%), promotion of urban ecology (15.8%) and improvement in air quality (9.5%) as the principal dimensions or perceived environmental quality of green innovation. The result further showed that green innovation characteristics have significant relationship with carbon storage. The study shows the importance of campus tree in carbon reduction and recommends the need for universities to give necessary recognition and incorporate these green components in physical planning.
