invasimapr vs nert: at a glance
What is invasimapr?
invasimapr halved its install size and became citable; the science stayed put.
invasimapr estimates species invasiveness and site invasibility from trait, environmental and resident-community data, exposing a traits → competition → invasion-fitness pipeline behind seven high-level wrappers. Its three releases are all packaging and standards work: a first citable archive in June 2026, then a maturity release bringing it in line with the B-Cubed software development guide. The one behavioral addition in that release is an opt-in standardise_inputs argument on compute_invasion_fitness(), off by default.
What is nert?
nert put fourteen TERN datasets behind one dispatcher and called it stable.
nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.

◆ Current state
invasimapr estimates species invasiveness and site invasibility from trait, environmental and resident-community data, exposing a traits → competition → invasion-fitness pipeline behind seven high-level wrappers. Its three releases are all packaging and standards work: a first citable archive in June 2026, then a maturity release bringing it in line with the B-Cubed software development guide. The one behavioral addition in that release is an opt-in standardise_inputs argument on compute_invasion_fitness(), off by default.
◆ Where it's heading
The pressure is toward being installable and auditable rather than more capable — install slimmed from roughly 100 MB to 56 MB, R CMD check warnings and notes resolved, sp moved to Suggests, a Darwin Core-aligned data dictionary added, and a Zenodo concept DOI with CITATION.cff, codemeta.json and .zenodo.json. The package moves in lockstep with its B-Cubed sibling dissmapr, tagged within minutes of each other at both 0.1.0 and 0.2.1, which points at project-level standards deadlines rather than independent release decisions. Trait dispersion metrics and scenario exploration remain on the roadmap.
◆ Prediction
Standards compliance is now complete and the roadmap names functional trait dispersion metrics and scenario exploration tools, so the next release is the first that can plausibly be about invasion ecology rather than packaging.
nert
0.0ANALYTICS
nert put fourteen TERN datasets behind one dispatcher and called it stable.
◆ Current state
nert is an R client for the TERN data API, reaching its first stable release in May 2026 after a year of milestone-tagged development. Version 1.0.0 exposes eleven functions covering fourteen datasets — SMIPS, ASC, AET, eight SLGA soil attributes, Soil Beta Diversity, Canopy Height and Land Surface Phenology — through a single read_tern(dataset_id, ...) dispatcher plus collect_tern_data() for batch extraction across locations and date ranges. Coverage sits at 83% overall with every reader at 100%.
◆ Where it's heading
The release history is unusual in that most of its tags are not releases: Milestone 1, 2 and 4 were pushed within eight minutes of each other in July 2025 purely as grant reporting and audit markers, with no user-facing content. What the 1.0.0 notes emphasise instead is test discipline — 310 deterministic offline tests, snapshot pins on every TERN bucket path and filename template, and mocked COG reads so R CMD check never touches the network. That is a client built on the assumption that the remote API's URL structure will change underneath it.
◆ Prediction
The notes describe pre-CRAN review polish and itemise remaining check NOTEs in cran-comments.md, so the next move is most likely a CRAN submission rather than additional dataset coverage.
