Our Services

How can we help?

Areas of Expertise

The services provided by Hdom are:

Hdom services forestry forest inventory redd


We provide a range of specialized services in the forestry area. Our differential is the quality and knowledge of the logistics for field work in Amazonian forests.

Forest Inventory

This service aims to establish permanent or temporary plots in primary vegetation in order to collect information that will later be used to estimate biomass (carbon) above and under the ground, in the target area of the project. This entire process is carried out using the MRV (Measurement, Reporting and Verification) method that provides transparency. Hdom also uses a quality system (QA/QC) to increase reliance on the data (information) delivered.


This service aims to conduct a study of the (whole) biomass according to the parts of the whole (diameter at breast height – DBH) in order to calibrate the equation that will be held to determine the carbon stock of the target area. This activity involves a destructive process of plots and laboratory analysis of samples collected.

Forest Management Plan (FMP)

The process involves from survey of volume stocks (diagnostic forest inventory, sampling and census) to the preparation of the wooden exploitation plan in the target area. The Forest Management Plan (FMP) is a technical document which, after drawn up, must be submitted to the relevant environmental agencies.

Integrated Management Plan of the Territory

The purpose of this study is to analyze the forest area as a whole, in its different aspects (wood, biodiversity, water, carbon, etc.), and create an exploitation plan that best optimizes their resources sustainably.

Hdom services biodiversity fauna flora


With experience in the study of flora in Amazonian forests, we assembled teams that, often integrated into forest inventory, perform collection and botanical identification. We also provide consulting services to companies seeking LIFE Certification.

Floristic Inventory

This service involves installing plots of equal size and subsequent collection of botanical material from vegetation located within such plots. Exsiccations are produced from collections for botanical identification and, where source materials (flowers, fruits and seeds) are present, these are also collected and stored as recommended by the technical standards.

Consultancy for the LIFE Certification

We assist companies and institutions in preparing for LIFE Certification.

Activities involve supporting the evaluation of impacts on biodiversity by the organization and subsequent assistance in project planning in order to mitigate or compensate such impacts. This should be done through a range of concrete actions to preserve the biodiversity, which are addressed on a priority basis.

Hdom services socio-environmental


We operate in the socioenvironmental area and environmental education by providing services intended to integrate the human being to sustainable development projects.

Awareness Activities

These are activities carried out on specific dates and occasions like dates disseminated by the media (environment day, arbor day, conscious consumption day, etc.) to raise awareness among employees of your company within a Environmental Education Program. Hdom can organize mini-workshops (working practical know-how or procedural skills), interactive lectures (using visual aids), guided tours, games etc., in order to integrate the company into society.


The purpose is to develop a curriculum within an Environmental Education Program for Workers [Programa de Educação Ambiental para Trabalhadores], which will be applied on a regular basis within the company as part of the mitigation measures or compensation of the enterprise. We approach this work by means of: (a) survey of environmental management activities; (b) survey of environmental perceptions; (c) preparation of the educational program and implementation of the training; and (d) compilation of information collected and presentation of results.

Socioenvironmental Diagnostics

Also known as Socioeconomic Diagnostics, this service involves the description of the profile of the communities that are directly or indirectly involved with the management and use of natural resources, thus enabling effective environmental sustainability of the proposed project. Some activities in this context involve: (a) identifying the impacts of the main activities undertaken by the population and in the surroundings; (b) providing alternatives to activities that produce adverse impacts in the project area; (c) submitting recommendations for the management, etc.

Engagement of stakeholders

Holding workshops using participatory methods to engage stakeholders involved in the proposed environmental sustainability project, aiming at developing the materiality matrix.

Definition of safeguards

This service is intended to define, through workshops using participatory methods, criteria for social and environmental safeguards that promote coordination and active participation of different interest groups and local communities, for the perfect understanding of the initiatives, strengthening the open dialogue between the parties, ensuring good governance of the territory and permanence of the environmental sustainability project.

Hdom services envirnmental assets generation carbon credits

Environmental Assets

We provide a range of specialized technical services in the area of Payment for Environmental Services (PSA) aimed at creating environmental assets for future commercialization and/or compensation.

Feasibility Study

Working together with our partners, we developed technical and economic studies aimed at understanding the feasibility of the project to create environmental assets. The purpose is to collect data that can be used within the decision process of performing (or not) the proposed development.

Estimation of carbon stock

The purpose of this service is to estimate, within a known range of error, the carbon stock (or biomass) present in the target area of the project. For such, the process uses primary data collected through a forest inventory and statistical methods that are known from the literature.

Drafting of baseline

The drafting of a baseline is required for projects that generate environmental assets within a financial mechanism called baseline-and-credit. To this end, we elaborate a possible and believable scenario that aims to estimate the quantity of environmental assets generated within a timeline.

Drafting of PDD

The Project Design Document (PDD) is a highly technical document where the applicant or owner of the project provides the basic information of the project. We have developed this document based on information collected in the field by following the models established by the validating entities of environmental assets.

Hdom services gis geoprocessing deforestation modeling

Environmental Analysis (GIS)

Using a Geographic Information System (GIS), we provide services of analysis and projection of changes in land use involving the preparation of maps for various purposes.

History and projection of deforestation

The purpose of this service is to assess, within a timeline, successive satellite images in order to determine the change in land use within the target project area. From this study, an algorithm is implemented to predict the advance of deforestation based on the history of that area. To this end, in both cases maps are drawn for better visualization of the process.


Using a Geographic Information System (GIS), we provide mapping services for various purposes, such as characterization plant and descriptive memorandum of rural property, which is required to the Rural Environmental Registry [Cadastro Ambiental Rural] (CAR).

Hdom services Rural Environmental Registry


We provide specialized technical services aimed at adapting the owner of rural area to the new Forest Code, including adherence to the Rural Environmental Registry [Cadastro Ambiental Rural] (CAR).


The purpose of this service is to assist the landowner to fulfill the obligations of maintaining native vegetation, developing and implementing a Plan for Recovering Degraded Areas (PRDA) in Areas of Permanent Protection (APP) and Legal Reserve (LR).

Process follow up

Hdom provides filing services and technical support regarding the Rural Environmental Registry (CAR) process with the competent environmental agency in Manaus (IPAAM). This includes filling out the landowner’s application form and subsequent follow up of the process.

Representation with the BVRio

Hdom is accredited with the Green Allowance Program of the State of Rio de Janeiro [Bolsa Verde do Rio de Janeiro] (BVRio) to register and represent landowners who want to sell their Environmental Reserve Quotas [Cotas de Reserva Ambiental] (CRAs) and, previously, Development Agreements and Sale of Environmental Reserve Quotas [Venda de Cotas de Reserva Ambiental] (CRAFs).

Training Courses

In partnership with the National Institute of Amazonian Research [Instituto Nacional de Pesquisas da Amazônia] (Inpa), we have developed training courses and extension in several areas of operation of the company.

Hdom dendrology course

Dendrology Extension Course

The Dendrology Extension course is an initiative of the partnership between Hdom Engenharia e Projetos Ambientais and Laboratório de Manejo Florestal [Forest Management Laboratory] (LMF) of the Instituto Nacional de Pesquisas da Amazônia [National Institute of Amazonian Research] (Inpa), where the company is established. In this course the student will have the opportunity to perfect his/her knowledge in Dendrology through an immersion that gathers theory and hands-on activities. The course includes the participation of field-trained professionals with extensive experience in botanical collections in the Brazilian Amazon.


9-13 November, 2015.


Mode of immersion in the Experimental Station of Tropical Forestry – EEST/Inpa (ZF-2).

Target Audience:

Students and / or professionals who work in the environmental field and have performed the disciplines of Taxonomy, Dendrology (or related field) and have some skill in field practices.
