The detection of LCC palm tree and the implementation of auxiliary field methods to estimate babassu density is an important first step to monitor this industry resource that is extremely important to the Brazilian economy and thousands of families over a large scale.
Our calculations regarding resource availability indicate that 6870 ha contained 25,015 adult babassu palm tree, with an annual potential productivity of 27.4 t of almond oil. In turn, 60% of the stage 5 babassu individuals were detected, showing significantly a different total height and a different number of leaves from the undetected ones. These individuals had significantly smaller stipes than the undetected ones. Approximately 96% of the babassu individuals in stage 6 were detected. A principal components analysis showed that the structure of the studied species differs from other species. The algorithm recognized individuals in life stages 5 and 6, and the extraction percentage, branching factor and quality percentage factors were used to evaluate its performance. We used the "Compt- palm" algorithm based on the detection of palm tree shadows in open areas via mathematical morphology techniques and the spatial information was validated using field methods (i.e. We also propose auxiliary methods to estimate the density of the LCC palm tree Attalea speciosa (babassu) based on the detection results. Here, we analyze the automatic detection of large circular crown (LCC) palm tree using a high spatial resolution panchromatic GeoEye image (0.50 m) taken on the area of a community of small agricultural farms in the Brazilian Amazon. This paper seeks to contribute knowledge regarding the use of these technologies by studying randomly dispersed native palm tree. High spatial resolution images as well as image processing and object detection algorithms are recent technologies that aid the study of biodiversity and commercial plantations of forest species.

USDA-ARS?s Scientific Manuscript databaseĬommercial-crop and ornamental palm trees serve important functions in tropical and subtropical regions of the world, and considerable precautions are taken each year to identify and control infestations of a variety of different insect pests. According to our study, people working in this occupation should take necessary precautions.Īcoustic Detection of Insects in Palm Trees In our study, allergic rhinitis and asthma were more common in palm tree garden workers than in the general population. These symptoms in both workers and office employees were higher in spring. The symptoms of allergic rhinitis (including sneezing, runny nose, and blocked nose) were significantly greater in palm tree garden workers (P=0.038).

Furthermore, in this study, no significant relation was observed between the prevalence of asthma and contact with dust, contact with pets' skin and hair, family history of asthma, or the use of perfume and air freshener. However, no relationship was observed between age, duration of employment, smoking cigarettes, hookah, or opium addiction with asthma. The correlation between asthma and occupation was significant ( P=0.046) and asthma prevalence was higher in palm tree garden workers. Descriptive statistics, chi-square test, t- test, and logistics regression were used to analyze data. Data collection included demographics, as well as standard International Study of Asthma and Allergies in Childhood (ISAAC) and A New Symptom-Based Questionnaire for Predicting the Presence of Asthma (ASQ) questionnaires. This was a cross-sectional study including 50 palm tree garden workers and a control group of 50 office employees. The present study aimed to investigate the correlation between asthma or allergic rhinitis and employment in the palm tree gardens of Jahrom, Iran.

Palms should also qualify because arborists care for them, and arborists care for trees, right? My introduction to botany class defined trees as plants that produce wood.
As usually tall, peremrial plants with roots, stems, and leaves, palms seem to qualify. Palms are real, but are they really trees? The answer depends on definitions.
