The Tree Plan (Plan Árbol) is CIUQ´s investigation with the collaboration of the University of the Army Forces’ University - ESPE´s Faculty of Engineering in Geospatial Technologies. The objective of this investigation is to know the state of urban trees on the sidewalk in 13 areas of the central plateau of Quito and to evaluate the environmental and ecosystemic services that they provide according to urban needs.
The objective was to establish the first geographic database of Quito's trees as an input for environmental monitoring and multidisciplinary research on the city's trees in the long term. For this purpose, information about location, height of the trees, state and width of the sidewalks were taken using orthophoto mosaic, obtained through unmanned aerial vehicle (UAV) and synchronized in ground with control points with a high precision GPS. Through field trips, photographic records of the trees were integrated into the geographic database.

The phase objective was to evaluate the diversity and functionality of Quito's trees based on the information collected in the first phase. Second objective was to make recommendations to improve the environmental and ecological efficiency of city's trees. For this purpose, a spatial analysis of variables associated with biological diversity (ie origin of the species, basic physiognomic and physiological characterization and reproduction strategy) and the state of maintenance of the urban trees (age, foliage density, canopy continuity and pruning) were carried out at the time of the acquisition of the photographic records.
The third phase explores the relationships between the characteristics and conditions of trees and those of the urban infrastructure of the public space. Width, state and spatial distribution of sidewalks and central sidewalks were studied using parameters such as tree height, trunk width and species to which it belongs in order to propose guidelines that harmonize these two elements for the benefit of the pedestrian.

His research and consulting scope includes the historical transformation of urban greenery and the implications for the environmental sustainability of the city. On this topic he has published Historical Urban Landscape as a Descriptive Feature for Risk Assessment: the ‘Quebradas’ of Quito (Proceedings of the First International Conference on Urban Physics 2016) and Ecological Urbanism, the environmental challenge of Quito (GEOPUCE 2011).
She designed the Multifunctional Urban Green Imbrica and peri-urban Geodiversity Reserves for YES Innovation within the proposal led by Arch. PhD Grace Yépez for the Ideas Contest “Corredor Metropolitano de Quito” (2020, winning proposal).
She has been a researcher and university professor in Biogeography, Ecology, Natural Resources and Protected Natural Areas. Among her outstanding research projects are "Ecological Roof: the potential of native plants in green roofs in Quito" (2010-2019) and "environmental consequences of the transformation and loss of montane forests" (2005 -2019)
