“…INFR (distance to infrastructure) showed up in three models and had a positive association with health, corroborating past findings by Koeser et al, [19], where expanding widths from sidewalk to curb improved tree condition, and research by Sanders and Grabosky [81], where tree growth increased in wider parking lot cut-outs. In contrast, ERA (estimated rooting area) yielded mixed results in our health analysis, after being the most strongly correlated-to-tree health variable in the RUSI model [72]. One possible explanation is that trees in this study are still in the younger stages of their life cycle, and rooting area may be less limiting at their current size [4].…”

“…Health was rated using the method outlined by Bond [71] -classifying growth, opacity, ratio, quality, and vitality into 20% scoring classes. Among the site-related predictor variables assessed in this study were those detailed by Scharenbroch et al, [72] in their creation of the Rapid Urban Site Index (RUSI). The index was modified for this study, though the following factors were replicated exactly as detailed: distance to infrastructure (INFR), estimated rooting area (ERA), soil texture (TXT), soil structure (STRC), surface (SURF), wet aggregate stability (WAS), crown light exposure (EXP), A-horizon depth (AHOR), and electrical conductivity (EC).…”

“…Interestingly, increased EXP (crown light exposure) reduced ratings for palm quality, as well as, shade tree quality and vitality. In the RUSI system, increases in exposure are associated with higher (more beneficial) scores [72]. However, [39] attributed excessive sun exposure paired with irrigation cessation several years after planting as a potential factor of tree death in East Palo Alto, California.…”

Urban tree planting initiatives can experience high levels of mortality during establishment years. Mortality tied to the stresses of transplanting can be partially negated or exacerbated depending on the species selected, nursery materials used, site conditions present, and management practices employed. Past research has quantified post-planting survival, health, and growth. However, varying climates, species, land use types, and management practices warrant additional region-specific research. The purpose of this study is to assess the success of plantings along Florida highways and identify species, site, and management factors related to tree and palm health and establishment. Results show high annual establishment survival (98.5%) across 21 planting projects ranging from 9 to 58 months after installation, (n = 2711). For transplanted palms, the presence of on-site irrigation significantly improved establishment from 96.2% to 99.4%. No establishment differences were detected with regard to irrigation treatment for small-stature trees, shade trees, and conifers. Additionally, there were significant differences in tree health response among tree groups given species, management, and site factors.

“…Entretanto, o estresse ambiental e as práticas de manejo inadequadas, como a poda drástica, predispõem a árvore ao ataque de pragas e doenças, o que acaba por causar o declínio da condição geral, do seu equilíbrio, da apresentação estética e de sua longevidade (HARRIS;CLARK. MATHENY, 1999;SCHARENBROCH et al, 2017), e por consequência podem afetar a quantidade e qualidade de determinados benefícios (KOESER et al, 2013).…”

“…Diferentes estudos têm utilizado a avaliação da qualidade das árvores urbanas para expressar o desempenho delas diante das adversidades de crescimento nas cidades (KOESER et al, 2013;NORTH et al, 2017;SCHARENBROCH et al, 2017), por outro lado não existem estudos que correlacionem diretamente a condição geral das árvores com a qualidade e quantidade de benefícios ofertados.…”

As árvores precisam apresentar boas condições de desenvolvimento e vigor para que possam ofertar o máximo de benefícios nas áreas urbanas. O presente estudo teve como objetivo mensurar o vigor de árvores de duas espécies florestais plantadas em praças da cidade de Irati, Paraná. Por meio de um protocolo, árvores de Lagerstroemia indica e Ligustrum lucidum foram avaliadas e separadas em duas classes subjetivas de vigor (boa e ruim). Para testar a adequação desta classificação foram mensuradas quatro variáveis em cada árvore (comprimento do ramo da última estação de crescimento, distância dos entrenós, comprimento da inflorescência e área das folhas) comparando-se os dados, aos pares, por meio do teste de Wilcoxon-Mann-Whitney. Com exceção da área foliar para L. indica, houve diferença significativa (p<0,01) entre as duas classes, com maiores valores para a classe de vigor boa, para todas as variáveis. Conclui-se que as variáveis analisadas se demonstraram adequadas para distinguir as duas classes de vigor e podem ser utilizadas para demonstrar a qualidade das árvores nas áreas urbanas.
